Description:
SYSTEM AND PROCESS FOR PRODUCING DRY MIX CONSTRUCTION MATERIALS WITH IMPROVED ENGINEERING PROPERTIES FIELD OF THE DISCLOSURE

[0001] The invention relates to a system and process for producing a variety of dry mix construction (DMC) materials as per the construction material grade requirements of end users. Specifically, the present invention provides a system and process which utilizes various industrial waste materials alongwith the traditionally used construction raw materials to produce various grades of dry mixed construction materials. More specifically, the present system and process solves end user problems such as construction grade selection for a specific structure construction, estimating water requirement for a specific structure construction, and easing the transportation and storage of raw materials required for a particular structure constriction.

BACKGROUND OF THE DISCLOSURE

[0002] Around the globe, there are various types of construction materials used in infrastructure development such as concrete, plaster, reinforced sawdust materials, iron, steel, glass, and/or wood. These construction materials are the most basic ingredients of any infrastructure development project. Further, the said construction and ancillary construction materials such as concrete, plaster, cement reinforced sawdust materials are highly versatile in nature i.e. malleable when newly mixed, yet strong when hardened. This versatile nature facilitates their use in building houses, skyscrapers, highways, bridges and other similar infrastructure construction projects.

[0003] To understand the versatile nature of the concrete, plaster, it is also important to understand the hydration process of a concrete material. In the hydration process, the concrete and plaster material gets physical change from a dry mixture material into a solid structure mass. This change in the physical property of the concrete material occurs due to the chemical reaction between cementitious materials and water. The hydration process does not only solidify the dry concrete and plaster materials into a solid structure mass but the said process is irreversible. Therefore, it is very important as to when water is mixed with said concrete and plaster materials.

[0004] Until the second half of the 20 th century, Site Mixed Concrete

(SMC) has been the major and only mode of facilitating the infrastructure development around the globe. Eventually, it was found that the traditionally followed methods of site mixing of concrete could no longer cater to the massive requirement for production and execution of concrete related works in the present socio-economic conditions. Also, the emergence of multistory buildings and the requirement for fast track constructions and higher quality norms made it impossible for employing site mixed construction materials to cater to the same.

[0005] Later, another concept called Ready Mixed Concrete (RMC) emerged as an effective solution to fill up all the bottlenecks mentioned as above, where it could be claimed that some of the problems faced by the customers were solved, but a complete one-stop solution could still not be provided to all categories of customers. RMC proved much advantageous over the traditional site mixed concrete as far as quantity of concrete required at site was concerned, but it still had flaws in the operational perspective like the deterioration in quality of concrete in case of delay of RMC at site. Also, the RMC employs use of transport (truck) which is a transit mixer that collects the RMC from the plants and carries it all the way to site. This way is also a lot costlier.

[0006] This led to the concept of Dry Mix Concrete (DMC) which allowed the user to use the concrete, and/or plaster mix after adding a certain amount of water thereto. However, the quality of concrete, and/or plaster to be utilized differs for different construction requirements such as floor, roof, pillars, and walls etc., thus the existing DMC cannot be used for all purposes due to unavailability of different grades of concrete for different jobs.

[0007] In order to solve the existing problems, a system is needed that can help solve problems such as "quantity of concrete and/or plaster" for SMC, "quality and cost issues of concrete and/or plaster" for RMC, and "grade-wise quantity and quality of concrete and/or plaster" for DMC. That is, a DMC product that is manufactured keeping in mind the specific structure construction requirements as well as the user requirements, along with means to provide DMC in sufficient amount.

[0008] Since, the concrete is most consumed construction material which requires raw materials extracted from natural resources such as coarse gravel or crushed rocks, limestones, granite, fine particles such as sand. Therefore, the extraction of raw materials to produce concrete adversely affects the environment.

[0009] On the other hand there are existing concrete manufacturing processes which propose utilization of waste products from various industries as raw materials to produce concrete and/or plaster materials. But the concrete and/or plaster materials thus produced do not always fulfil all the requirements of end users and thus fails in this regard. Moreover, such concrete and/or plaster materials as produced from the industrial waste materials require lot of knowledge with regard to the chemical and physical properties of the waste materials. Accordingly, a common laymen person is not always able to produce the desired concrete and/or plaster materials by utilizing various industrial waste materials.

[0010] Moreover, it is always desirable to reutilize various industrial waste materials to overcome the environment pollution as caused by high discharge of such industrial wastes. Accordingly, there is a demand for the reutilization of such industrial wastes in a useful manner like production of various different kinds of construction materials such as concrete, plaster, reinforced sawdust materials, and/or ancillary construction materials.

[0011] Hence, there is also a need of a system and process which can employ various waste materials as the starting raw materials in production of various construction materials. Further, there is also a need for a system and process which is user friendly, environment friendly and also helps in protecting the natural resources by reducing the burden of mining for various types of construction materials.

[0012] Therefore, a system and process is required that produces various different grades of most useful construction materials such as dry mix concrete, plaster and/or ancillary construction materials by using various industrial waste materials.

SUMMARY [0013] Aspects of the invention are thus directed to a system and process for producing a Dry Mix Construction material (DMC) such as dry mix concrete and/or plaster having structural properties as per the construction requirements of the end user. Further, the said DMC is prepared by utilizing industrial wastes, making the DMC environmental friendly as well as providing DMC as per the grade desired by user.

[0014] In light of the various problems disclosed regarding the existing systems and methods for producing such construction materials, present invention proposes a solution which not only produces dry mix construction material based on the user requirements, with improved structural properties, but also employs the use of various industrial waste materials. These waste materials are classified based on their particle size before producing different grades of dry mix construction material such as dry mix concrete and/or plaster. Thus, overcoming the problems of existing systems and methods.

[0015] In an aspect of the present invention, a system for producing dry mix construction materials such as dry mix concrete and/or plaster with improved structural properties is disclosed. The said system has a plurality of raw material storage compartments adapted for storing different raw materials (A, B, N) from different sources. Further, a material classification unit that segregates or classifies different raw materials into a plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ;

Ni, N 2 , N 3 , N n ). The process of classification is based on criteria including but not limited to, grade, particle size, physical state, source of raw material etc. In another aspect of the present invention, the shape of certain raw materials (A, B, N) is improved via the said process of classification and thus the said invention provides a construction material with improved engineering properties.

[0016] In an embodiment, the said material classification unit includes but not limited to a sieving unit, a vibratory/rotary ball mill, an air classification system such as a cyclonic separator, and the like. In another embodiment, the material sub-classes (Ai,

A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) obtained after classification are stored in different material handling compartments. [0017] In an aspect, a chemical dispersion unit that has various chemical materials (CMi, CM 2 , CM 3 , CM n ) stored in different chemical storage units (CSi, CS 2 ,

CS 3 , CS n ) is employed to add such chemical materials (CMi, CM 2 , CM , CM n ) to the said Dry Mix Construction material (DMC). In an embodiment, the amount chemical material added depends on the grade of construction material as desired by the user.

[0018] In another aspect of the present invention, a material selection unit works in conjugation with the material handling compartments, raw material storage compartments, and the chemical storage units (CSi, CS 2 , CS 3 , CS n ). The material selection unit has a control panel for selecting the type of construction material to be produced either depending on user requirements or automatically, and a command panel for controlling the operation of producing the DMC materials.

[0019] In an embodiment, the command panel of the material selection unit controls the operation by controlling the amount of raw materials (A, B, N), chemical materials (CMi, CM 2 , CM 3 , CM n ) etc. to be used in producing the said DMC materials.

[0020] In an embodiment, the material selection unit controls different components that help in producing the said DMC materials.

[0021] In another embodiment, the process utilizes commands generated by a material selection unit which controls the process of producing dry mix construction (DMC) materials. The said commands are different based on type of construction material to be produced and thus the ingredients or raw materials (A, B, N) involved in the process are varied accordingly.

[0022] In an aspect, the commands as generated are adapted to control the flow of raw materials (A, B, N) i.e. amount of raw materials (A, B, N) utilized is controlled by the commands generated by the material selection unit.

[0023] In another aspect, the process of producing dry mix construction materials involves using at least one of the chemical materials (CMi, CM 2 , CM 3 , CM n ) from the chemical dispersion unit that is blended along with at least one of the plurality of material sub-classes (Ai, A 2 , A3, A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 ,

N 3 , N n ) and at least one of the raw materials (A, B, N) in a blending unit.

[0024] In an embodiment, the present process of producing dry mix construction material transfers the produced dry mix construction material from the blending unit to a silo. The transport of the raw materials (A, B, N), chemical materials (CMi, CM 2 , CM 3 , CM n ), dry mix construction material etc. is facilitated by the conveyor. [0025] Therefore, the present invention provides a system and process for producing dry mix construction (DMC) materials such as dry mix concrete, plaster and/or ancillary construction materials with improved structural properties and of different grades depending on the user requirements.

[0053] In an embodiment the said dry mix blend contains cement for imparting hardening property, fine aggregates from sand material as a filer, fly ash and blast furnace slag for imparting pozzolanic activity and/or chemical materials (CMi, CM 2 , CM 3 , CM n ) for initial binding. Further, the said dry mix blend is suitable to be used as a dry mix construction ancillary product such as a dry mix plaster product (DMP). If the customer requires the said dry mix plaster then the said dry mix blend is packed as it is in the air tight bags and transported to the user. Finally, the said dry mix construction is mixed after ensuring the datum level of moisture and packed into air and water proof bags (F). Further, the present system provides a closed environment for producing a desired construction material, wherein the said closed environment provides a moisture free construction material and thus the overall system become zero error operating system (ZEOS). Such process provides a long lasting dry mix construction which have improved structural properties as well as which is easy for storage and transportation.

[0054] In an embodiment, the DMC produced and packed in bags (F) is utilized at the site after mixing it with particular amount of water as mentioned on the packaging bags (F). Finally, the said zero error operating system (ZEOS) provides a dry mix construction material as per the demand and requirements of the end customer or the construction specification data of a specific construction structure.

[0055] In a specific embodiment, the Fig. 2 illustrates the various system components adapted for producing a dry mix construction with improved engineering properties. The said system components includes a plurality of raw material storage compartments (202), a material classification unit (204), a chemical dispersion unit (220), a material selection unit (210), a plurality of conveyer belts (not shown), and a blending unit (240) adapted for blending at least one of the raw materials (A, B, N), at least one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), at least one of the chemical material (CMi, CM 2 , CM 3 , CM n ) as selected by the material selection unit (210) into a dry mix construction composition to be stored in a silo (270) for distribution. [0056] In an aspect, as illustrated in Fig. 2 the raw materials (A, B, N) from various sources are stored in respective raw material storage compartments (202). In an exemplary embodiment, the raw materials (A, B, N) are fly ash (Material A),

GGBS (Material B), and fine aggregate (Material N) such as sand, crushed sand, slag sand and the like. Further, the raw materials (A, B, N) are stored in material handling compartments (260) as material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 ,

N 3 , N n ) as per their grades, particle size, physical state, source of raw material and the like. The raw materials (A, B, N) are classified into material sub-classes (Ai, A 2 ,

A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) by the material classification unit (204).

[0057] Similarly, raw materials (other than raw material A, B, N) which are course construction aggregates (Y and Z) and the like, are also stored separately in material handling compartments (260).

[0058] These material handling compartments (260) are controlled by the material selection unit (210). The material selection unit is responsible to control the discharge of at least one of the plurality of raw materials (A, B, N), discharge of at least one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), and discharge of at least one of the chemical material (CMi, CM 2 ,

CM 3 , CM n ) as required to make construction material of a specific grade.

[0059] According to an embodiment of the present invention, the raw materials required for a specific grade of construction material are mixed in a blending unit (240). The blended mixture of specific grade of construction material is formed when at least one of the raw materials (A, B, N), at least one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), are blended alongwith at least one of the chemical materials (CMi, CM 2 , CM 3 , CM n ). The chemical dispersion unit (220) has plurality of chemical materials (CMi, CM 2 , CM 3 , CM n ), including but not limited to cellulosic material, starch material, lignosulphonate salt, stearate salt of alkali metal group or alkaline earth metal group, Sulphonated Naphthalene Formaldehyde, Poly Carboxylic Ether, hydroxide salt of alkali metal group or alkaline earth metal group and the like. The chemical materials (CMi, CM 2 , CM 3 , CM n ) are selected based on the grade of construction material required to be manufactured, by the material selection unit (210). [0060] In an exemplary embodiment, the system for producing DMC with improved structural properties employs the material selection unit (210) to control material classification unit (204), material holding compartments (260), chemical dispersion unit (220), blending unit (240), conveyors (not shown). That is, the material selection unit (210) uses automation to manufacture DMC with improved structural properties as per user/ site requirements. The DMC formed after blending in the blending unit (240) is transferred to silo (270) for dispatching and/ or storage.

[0061] In an aspect, the material selection unit (210) has a control panel and a command panel. The control panel is a processor implemented machine that serves as user interface (UI), and has a data storage device such as memory to store computer program and instructions/ commands for the command panel.

[0062] In an implementation, the control panel of the material selection unit (210) receives user requirements. These user requirements are then analyzed by the processor using computer program installed thereon. The analysis concludes the type of construction material that is best suitable as per user requirements. Accordingly, various commands are sent to the command panel regarding the manufacture of said type of construction material.

[0063] In another implementation, the command panel is responsible to discharge of raw materials (A, B, N) from raw material storage compartments (202), discharge of at least one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi,

B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) from material handling compartments (260), at least one of the chemical material (CMi, CM 2 , CM 3 , CM n ) from the plurality of chemical storage units (CSi, CS 2 , CS 3 , CS n ). Further, the command panel is also adapted to control the flow of the raw materials (A, B, N), the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), and chemical materials (CMi,

CM 2 , CM 3 , CM n ). Further, the command panel controls the blending unit (240), conveyors (not shown) and the silo (270) for dispatching/ storing the DMC.

[0064] In an aspect, the aggregates are dried through a drying system before the segregation/ classification starts. For example, aggregates are dried before classification, or keeping the combined moisture to be <0.5% before blending occurs in the blending unit (240).

[0065] In yet another exemplary implementation, the commands from the command panel of the material selection unit (210) are generated by a human, or an expert in operating the said system. This allows the customization in cases where the human has the expertise to produce a better DMC than what would be produced by the program. In addition to that, it gives the human to override the commands generated by the UI of the material selection unit (210).

[0066] In an embodiment, the said material classification unit (204) is selected from at least a sieving unit, a cyclonic separator, or a combination thereof. The said material classification unit (204) is configured to provide the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) based on a particle size grading of atleast one of the said plurality of raw materials (A, B, N) stored in raw material storage compartments (202).

[0067] According to various embodiments of the present invention, as illustrated in Fig. 3, a process (300) for environment as in Fig. 1 for producing a dry mix construction material starts at step (302) where the material selection unit initiates the process (300) after sending command from its command panel. As disclosed above, the material selection unit has control panel which receives the user requirements and generates commands to produce appropriate grade of construction material. These commands are executed by the command panel that controls various units, compartments, of the system as described in description of Fig. 2.

[0068] The next step (304) involves the use of material selection unit which segregates the raw material (A, B, N) from the raw material storage compartment by grade, size, physical state, source and the like. The segregated material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) are stored in separate material handling compartments. In an implementation, the said material classification unit is selected from at least a sieving unit, a cyclonic separator, or a combination thereof. [0069] In an embodiment, the chemical dispersion unit has a plurality of chemical materials (CMi, CM 2 , CM 3 , CM n ) stored therein. The chemical materials

(CMi, CM 2 , CM 3 , CM n ) are selected from a cellulosic material, a starch material, a lignosulphonate salt, a stearate salt of alkali metal group or alkaline earth metal group, Sulphonated Naphthalene Formaldehyde, Poly Carboxylic Ether, a hydroxide salt of alkali metal group or alkaline earth metal group. At step (306) based on the required grade of construction material to be produced for user, the chemical material(s) (CMi, CM 2 , CM 3 , CM n ) is/ are selected. [0070] At step (308), the command panel of the material selection unit controls the flow of raw materials (A, B, N) from the raw material storage compartments into to the blending unit. Further, the command panel also controls the flow of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N , N n ) from material handling compartments to the blending unit along with the flow of chemical materials (CMi, CM 2 , CM 3 , CM n ) from the chemical dispersion unit. The blending unit then is responsible for blending the raw materials (A, B, N), the material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) and the chemical materials (CMi, CM 2 , CM 3 , CM n ). [0071] At step (310), the blended mixture of raw materials (A, B, N), material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), and chemical materials (CMi, CM 2 , CM , CM n ) which is now called as DMC is transferred from the blending unit into the silos for dispatch and/ or storage. [0072] At step (312), the produced DMC is packaged in leak proof bags and transported to the site. At step (314), the DMC is readily utilized after adding a particular amount of water prescribed on the bag.

[0073] The above process (300) is mere an exemplary embodiment to show the complete environment including gathering of user requirements, producing the DMC as per desired grade and utilization of such produced DMC at site.

[0074] In an embodiment of the present invention, the system and process for preparing DMC employs the material selection unit to select the grade of the construction material based on the user requirements. The material selection unit has a control panel that runs a program to identify the best grade of construction material as per user requirements. The control panel then generates commands for the command panel to execute in order to produce such DMC. The commands generated have plurality of construction material data sets.

[0075] In an exemplary embodiment, each of the said plurality of construction material data sets are selected from a weight percentage level of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), a weight percentage level of the plurality of raw materials (A, B, N), a weight percentage level of the chemical materials (CMi, CM 2 , CM 3 , CM n ) or a combination thereof.

[0076] According to an embodiment of the present invention, the data storage device of the material selection unit (210) comprises a plurality of construction material data sets as illustrated in Fig. 4, and each of the said plurality of construction material data sets correspond to a dry mix construction specification as illustrated in Fig. 5.

[0077] The construction material data sets as illustrated in Fig. 4, is an exemplary data set segregated based on particle size. This data set is used in producing the DMC of various grades such as plaster mix, plain cement construction, pavement construction and the like.

[0078] Various grades of construction are illustrated in Fig. 5. For example, if the requirement is for RCC - M20 to M60, refer the table in Fig. 5. The ingredients required are cement, fine aggregate replacement, pozzolona for imparting pozzolanic activity, mineral admixture etc. Now the proportions of the said ingredients involved are selected from the table as illustrated in Fig. 4.

[0079] According to an embodiment, the system and process of the present invention employs a material selection unit that has a computing program alongwith a processor that is adapted to compare the construction specification as inputted by the user with at least one construction material data set (Fig. 5), and generates the plurality of commands as per the at least one construction material data set. Further, in another embodiment, the said computing program alongwith a processor is also replaced by an expert manual interface. The said expert manual interface provides an easy means to a user to compare the construction specification as required with at least one construction material data set. Hence, the system and process of the present invention provides an automated as well as a manual interface to compare the user required construction specification with at least one construction material data set.

[0080] In yet another embodiment, the said plurality of commands are selected from a name and weight percentage level of at least one of the plurality of raw materials (A, B, N), a name and weight percentage level of at least one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), a name and weight percentage level of at least one of the chemical materials (CMi, CM 2 , CM 3 , CM n ) or a combination thereof.

[0081] In an aspect, the said plurality of commands provides a plurality of dropping over a plurality of conveyer belts and/or alternate dispersion systems, wherein the said plurality of dropping are selected from at least a dropping of one of the plurality of raw materials (A, B, N), at least a dropping of one of the plurality of material subclasses (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), or at least a dropping of one of the chemical materials (CMi, CM 2 , CM 3 , CM n ) over the said plurality of conveyer belts.

[0082] The system and process for producing DMC with improved structural properties utilizes material selection unit with command panel to control the components involved and process of the present invention. The command panel controls the flow/ droppings of at least a dropping of one of the plurality of raw materials (A, B, N) from the raw material storage compartments, at least a dropping of one of the plurality of material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) from the material handling compartments, and/or at least a dropping of one of the chemical materials (CMi, CM 2 , CM 3 , CM n ) form the chemical dispersion unit. The said plurality of droppings is then blended in a blending unit and the dry mix construction material is produced.

[0083] According to an embodiment of the present invention, the process as illustrated in Fig. 6 illustrates the exemplary working of components of Fig. 2. The process starts at (602) where the plurality of raw materials (A, B, N) is stored in plurality of raw material storage compartments from different sources.

[0084] The next step (604) involves the use of material classification unit that classifies or segregates at least one of the raw materials (A, B, N) based on particle size as illustrated in Fig. 4.

[0085] The segregated raw materials along with non- segregated raw materials are stored separately in material handling compartments in step (606).

[0086] According to various embodiments, the process (600) is controlled by the material selection unit. Wherein, the material selection unit has a control panel including UI that is configured to receive user requirements. Further, control panel has a computer program that identifies particular grade of construction material based on the user requirements from a data storage device. The data storage device has various raw materials based on particle size (as in Fig. 4), this data is utilized to generate commands for the production of DMC that is user's requirement specific.

[0087] The step (608) describes how the user requirements are gathered including by inputting site area, or place (floor, wall, roof), or custom requirements etc. These requirements are gathered through UI of the control panel of the material selection unit.

[0088] A command panel of the material selection unit is responsible for executing the various commands generated by the control panel related to grade of DMC to be produced according to user requirements. The command panel controls the flow of raw materials (A, B, N), material sub-classes (Ai, A 2 , A 3 , A n ; Bi, B 2 , B 3 , B n ;

Ni, N 2 , N 3 , N n ), chemical materials (CMi, CM 2 , CM 3 , CM n ) and working of blending unit, conveyors etc. of present system. Therefore, step (610), the command panel procures different raw materials (A, B, N), material sub-classes (Ai, A 2 ,

A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) and/ or chemical materials (CMi, CM 2 ,

CM 3 , CM n ) and blends them in the blending unit to produce DMC as per user requirements. [0089] The produced DMC is then transferred to silo at step (612) where it is dispatched in bags to the site or stored for further use.

[0090] In an exemplary implementation, say a user requires "plaster mix" at his site. The present system and process of producing DMC provides the user with said construction material of improved structural properties (refer Fig. 2 and 6). Different raw materials (A, B, N) in the storage compartments (202) are classified and stored in material handling compartments (260). Few raw materials (A, B, N) are classified by material classification unit (204). Since, the user requires "plaster mix" as final product, the said DMC is input through the control panel of material selection unit (210).

[0091] The control panel has a computer program stored therein which selects a particular construction material data set from a data storage device. Corresponding to the construction material data set selected, the control panel generates commands and sends them to command panel of material selection unit (210). Since, the command panel controls various components of the system as disclosed in Fig. 2, it selects the raw materials (A, B, N), the material sub-classes (Ai, A 2 , A 3 , A n ; Bi,

B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ) and/ or chemical materials (CMi, CM 2 , CM 3 , CM n ) as required for the production of "plaster mix". Further, in another embodiment, the said control panel alongwith the said computing program is also replaced by an expert manual interface. The said expert manual interface provides an easy means to a user to compare the construction specification as required with at least one construction material data set.

[0092] (Refer Fig. 5) For every 400-600 grams of cement, 600-800 grams of fine aggregate replacement, 200-300 grams of normal pozzolana (similar to flyash/ GGBS) is required to make "plaster mix". (Now refer Fig. 4) Also, to produce fine aggregate replacement, fine aggregate of (0 to75 mic + 75 mic to 600 mic + 600 mic to 2.36 mm + 2.36 mm to 4.75 mm), fly ash of (0 to 150 mic) and GGBS of (0 to 150 mic) size is procured from respective material handling compartments (260). Similarly, for normal pozzolana, fly ash and GGBS of Blaines fineness of 3200 to 4000 each is procured from material handling compartments (260).

[0093] As disclosed in Fig. 2, the material sub-classes (Ai, A 2 , A 3 , A n ;

Bi, B 2 , B 3 , B n ; Ni, N 2 , N 3 , N n ), and/ or chemical materials (CMi, CM 2 , CM 3 , CM n ) are transferred in the blending unit (240) with conveyors (not shown). The blending unit (240) blends at least one of the plurality of material sub-classes (Ai, A 2 ,

A 3 , A n ; Bi, B 2 , B 3 , B n ; Ni, N 2 , N3, N n ) and/ or chemical materials (CMi, CM 2 ,

CM 3 , CM n ) as selected by the commands of the command panel of material selection unit (210) and transports the produced DMC (plaster mix) to the silo (270).

[0094] Based on the requirements of the user, the produced DMC is packet in bags of different volumes and shipped to site where they can be readily utilized after adding particular amount of water thereto. [0095] The same process is repeated for RCC, pavement construction material and other DMC by different commands generated by control panel and controlled by command panel of material selection unit.

[0096] In an exemplary embodiment of the present invention, Fig. 7 illustrates step by step flow 700 for the raw material process management block diagram as disclosed earlier in Fig. 6: i. Natural river sand (702), if abundantly available in the particular region and if the fineness modulus and gradation are perfectly matching the desired requirement, then such natural sand is directly used as a fine aggregate for production of construction materials. In case of absence of natural river sand, crushed stone sand or Iron slag sand (702) is used as either total or partial replacement of fine aggregate, provided the fineness modulus (FM) and gradation are matching the desired requirement (refer Fig. 4 for requirements); ii. In case the above two parameters are not matching the requirements (704), the fine aggregate is diverted to a screening plant and stored in separate sand silos (706) containing different fractions to be blended later by automated processes to acquire almost the exact FM and gradation, and further to be used for construction material production; iii. Coarse aggregate of 5-10 mm (non-VSI material) size is the fraction that is abundantly available in any crushers (708) for which the consumption and/or production ratio is very low as compared to other size fraction aggregates, such as 20 mm down aggregates; iv. In case a sand manufacturing/processing unit (710) is strategically planned to be adopted as functionality, this fraction of 5-10 mm aggregate may be used as a raw material (A, B, N) for producing the processed sand; v. The processed sand is then diverted to a screening unit (706), which is then stored in different silos, later to be blended in appropriate proportions (724) to achieve the desired properties for construction material production of various natures and requirements. This is a customized process forming an integral part of the step by step flow 700 illustrated in Fig. 7. This becomes the primary output of the sand processing unit (710).

[0097] It is also evident that a maximum datum level of moisture content has to be determined and/or set for the production of dry construction materials. Specifically, the said datum level of moisture contents for the production of dry construction materials is set to a maximum level of 0.5%. Further, it is most preferred to bring down the moisture content of raw materials to the moisture datum level as set for the final dry construction materials. For instance, if the moisture datum level for the is frozen as to a maximum level of 0.5%, then the raw materials or aggregates (i.e. fine aggregate in particular) have to be dried in a pre-designed dryer to bring down the moisture level to 0.5%.

[0098] Further, it is most preferred to maintain a closed/semi-closed environment during the production of the dry construction materials so that there is no extra increase in the moisture level during the entire production process. Accordingly, the present system provides a closed/semi-closed environment with a defined time dependent packing strategy for producing a desired construction material. The said closed/semi- closed environment with said time dependent packing strategy ensures that there is no extra increase in the moisture level of the dry mixed construction materials. [0099] In an embodiment, an efficient fuel which is techno-commercially viable has to be utilized to operate the said pre-designed dryer. Kerosene or other petrochemical liquid fuels is not found to be commercially viable, also due to its comparatively lower calorific value.

[00100] After careful consideration and commercial analysis, if coal of very high calorific value is used as raw fuel for operating the said pre-designed dryer then such coal combustion will also produce a high quality of coal ash. vi. This coal ash (714) from coal of very high calorific value (712) is analyzed for its mechanical and chemical properties for the feasibility of using it as a cement or sand replacement. vii. If found that in its original condition, the coal ash satisfies the relevant standards and qualifies as a cement replacement, it is directly pumped into fly ash silos to be used as a cement replacement. viii. If found that it requires some alteration in its properties, the coal ash may be diverted to a grinding/classification unit (716), which segregates the ash into coarser and finer fractions. ix. The coarser fractions, are directly diverted to sand silos of different fractions, hence used later by blending in appropriate proportions (724) to acquire the desired properties of fine aggregates to produce construction material. x. The finer fractions, are diverted towards fly ash silos, to be used as a cement replacement for production of construction material. xi. Fly ash from an external source (722) may also be subjected to the same processes as described through steps i-x. xii. If Ground Granulated Blast Furnace Slag or GGBFS (726) is chosen instead of fly ash, then as illustrated in the step by step flow 700 of Fig. 7, GGBFS may undergo the same process as explained through steps i-x. xiii. Cement (730), is appropriately chosen based on its established quality parameters, basically the strength, geographical availability, reputation of the company as well as the particular technical requirement of the jobs considered. xiv. VSI aggregate below 10 mm size, 20 mm coarse aggregates, admixtures (in powder form) is blended along with processed fine aggregate as well as processed cementitious materials in the appropriate proportions as per the standard mix designs, hence ensuring optimum quality of construction material being produced. It is made sure that the shape of the aggregates chosen is well acceptable. xv. Admixtures (728) are almost always in powder form. They are stored in separate bins which are dispersed through appropriately designed dry dispensers into the central mixer, through an advanced mechanically designed system. xvi. The step by step flow 700 as illustrated in Fig. 7 therefore produces a dry mix construction material/mortar/plaster/screed based on the parameters best for user requirements.
