A method for preparing concrete

Abstract

The invention belongs to the technical field of concrete preparation and discloses a concrete preparation method. In the concrete preparation method, the concrete preparation device used includes a driving mechanism, a screening mechanism, a stirring mechanism and a water supply mechanism fixed on the mounting frame; the driving mechanism is respectively connected with the screening mechanism, the stirring mechanism and the The water supply mechanism is connected, and drives the screening mechanism, the stirring mechanism and the water supply mechanism to work; the screening mechanism includes a first screening mechanism and a second screening mechanism, and the second screening mechanism Located between the first screening mechanism and the stirring mechanism, it is used to directly feed the stirring mechanism; the second screening mechanism is connected to the water supply mechanism, and performs synchronous feeding and Inject water. By adopting the concrete preparation method of the invention to carry out concrete preparation operation, the production quality of concrete can be improved.

Description

A kind of concrete preparation method technical field The invention belongs to concrete preparation technical field, be specifically related to a kind of concrete preparation method. Background technique Concrete usually refers to taking cement as the main cementitious material, and mixing it with water, sand, and stones, if necessary, mixing chemical external materials. Additives and mineral admixtures, and in accordance with scientific proportions, go through the processes of uniform stirring, compacting, curing and hardening. Production of obtained artificial stone. Concrete is rich in raw materials, low in price, low in production cost, and has good plasticity. It has the advantages of high strength, good durability, available steel reinforcement, corrosion resistance and long service life. However, there are following problems in the production process of existing concrete: 1, when traditional sieving device carries out sieving work, larger sand and gravel ma...

AI Technical Summary

Problems solved by technology

[0004] 1. When the traditional screening device performs screening work, larger sand and gravel materials are easy to block the screen, which reduces the screening efficiency;

[0005] 2. Theoretically, in order to improve the mixing quality, the materials with low density should be put into the mixing first, and then the materials with high density should be put into the mixing step by step. However, in most cases, the order of feeding and the proportional relationship are ignored in order to improve the efficiency, which will easily cause the concrete to mix poorly. Adequate, poor homogeneity, honeycomb phenomenon
