Document Type and Number:
WIPO Patent Application WO/2021/072704
Kind Code:
A1
Abstract:
Disclosed is a cement and admixture pre-stirred concrete production method, comprising: firstly feeding a cementing material, an admixture and some of water into a stirrer according to a ratio, carrying out stirring until a cement is completely hydrated and completely reacts with the admixture, then adding an aggregate material, and stirring same with the remaining water. An apparatus using the method comprises: a gravel storage hopper, a cementing material storage hopper, an admixture metering barrel, and a water metering box, which are arranged above a stirring main machine respectively, wherein a gravel discharging door is arranged at the bottom of the gravel storage hopper and leads to the stirring main machine; a cementing material discharging door is arranged at the bottom of the cementing material storage hopper and leads to the stirring main machine; the admixture metering barrel and the water metering box are in pipeline communication with the stirring main machine by means of a three-way joint; a metering pressure pump is arranged on a pipeline between the water metering box and the three-way joint; and valves are arranged on the pipelines of the admixture metering barrel and the water metering box respectively. Compared with a traditional method, in the production method the admixture mixing amount is reduced by 10%-20%, the concrete production cost is reduced, and the concrete strength is improved.
