Preparation process of concrete

Abstract

The invention discloses a preparation process of concrete. The preparation process comprises the following steps of 1, controlling a first stone screening assembly to move downwards to open a feedingport, and adding a cementing material, water, an additive and an admixture required for preparing the concrete into a shell; 2, putting broken stones into the first stone screening assembly, controlling the first stone screening assembly to conduct preliminary screening on the broken stones, after it is detected that the weight of the stones in the first stone screening assembly is not changed, controlling the first stone screening assembly to move upwards to close the feeding port, and meanwhile, enabling the large broken stones in the first stone screening assembly to fall into a second stone screening assembly; 3, controlling a stirring assembly to stir the materials in the shell; and 4, after the concrete is stirred and formed, opening a discharging opening of the shell, and sending out the concrete from the discharging opening. The preparation process of the concrete is simple to operate, and the preparation of the concrete can be quickly completed.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to a concrete preparation process. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. It is uniformly stirred, densely formed, cured and hardened. Concrete has, It has the characteristics of high compressive strength, good durability and wide range of strength grades. At present, the existing concrete production and manufacturing usually have the following deficiencies: 1. The existing equipment cannot effectively screen the crushed stone materials when preparing and processing the concrete, resulting in easy inclusions in the finished materials after mixing Large crushed stones affect the subsequent processing and use of finished materials; 2. In the existing technology center, the screening ...

AI Technical Summary

Problems solved by technology

At present, the existing concrete production and manufacturing usually have the following deficiencies: 1. The existing equipment cannot effectively screen the crushed stone materials when preparing and processing the concrete, resulting in easy inclusions in the finished materials after mixing Large crushed stones affect the subsequent processing and use of finished materials; 2. In the existing technology center, the screening machine can only screen crushed stones of one size. If the screening size needs to be changed, it is time-consuming to replace the screen mesh 3. Concrete preparation equipment that can be screened usually has the problem of gravel clogging the screen holes, resulting in low filtration efficiency and affecting the concrete production schedule
