Concrete preparation method

Abstract

The invention belongs to the technical field of concrete preparation, and discloses a concrete preparation method. According to the concrete preparation method, a used concrete preparation device comprises a driving mechanism, a screening mechanism, a stirring mechanism and a water supply mechanism which are fixed to a mounting frame; the driving mechanism is connected with the screening mechanism, the stirring mechanism and the water supply mechanism and drives the screening mechanism, the stirring mechanism and the water supply mechanism to work. The screening mechanism comprises a first screening mechanism and a second screening mechanism, and the second screening mechanism is located between the first screening mechanism and the stirring mechanism and used for directly feeding the stirring mechanism; the second screening mechanism is connected with the water supply mechanism and is used for synchronously feeding and injecting water into the stirring mechanism. When the concrete preparation method is used for concrete preparation operation, the production quality of concrete can be improved.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a concrete preparation method. Background technique [0002] Concrete usually refers to cement as the main cementitious material, which is mixed with water, sand, stones, chemical admixtures and mineral admixtures if necessary, and is uniformly stirred, densely formed and cured according to the scientific mixing ratio. Artificial stone produced by other processes. Concrete is rich in raw materials, cheap in price, and low in production costs. It also has the advantages of good plasticity, high strength, good durability, reinforcement with steel bars, and long corrosion-resistant service life. [0003] However, there are following problems in the production process of existing concrete: [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 effi...

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
