5-Description of the Invention:

This unperceived above Innovation : (The Smart Bizzam Tropical Joint less Brick) is based on the necessity of finding integrated site solution for an alternative Substantial, Cheap and Long Lasting Building Material units, enabling poor dwellers, low income citizens and even rich ones obtaining that hygienic home, school, hospital and other domestic, public and official premises that shelter them against severe weathering conditions, storms fire attack / spread or any other environmental threads, provided that considerable job opportunities it preserves, beside realizing that relief, friendship and coexistence with the surrounding environment, enhancing that forecasted prosperity and achieves welfare of the beneflters, rather than that flammable grass huts and muddy cottages framed with timber woods scattered all through the urban villages, particularly in Great Cordofan rural provinces and localities. The new born Product can be manufactured from normal clean valley sand eighth (1/8) inch: quarter (1/4) inch rough aggregate and: Natural lime added to few Portland cement (7: 5: 1), well mixed to 10% clean soft water (Ph. value = 8.1). Other alternatives of (lime/ cement) are Fiber Mesh, (Juss) and powdered calcium carbonates added to few (klincker) or any other adhesive material, in the same above ratio, as this mold meets the required quick setting, improve thermal insulation, minimizes both weight and workmanship efforts and enhances other physical properties, in favor of that Smart unperceived technique of cavities and unique size of the Brick (16cm. X 48cms. X 16cms. 13 units of which are required to erect one squared meter of 16cms Thick Wall, compared to 12 units, 20cms thick heavy block wall and 160 peaces for the same thickness of Brick wall. The total weight of that (Bizzam) Wall is Only Two Thirds of that of Block wall and Three Fifth of Brick one. The Compression Stress of which is 4.4 N/sq. mm. Compare to 4.2 N/sq. mm of that manufactured from Portland cement / sand mix ratio
