Hierarchical multi-grade type concrete mortar preparation material mixing treatment technology

Abstract

The invention relates to a hierarchical multi-grade type concrete mortar preparation material mixing treatment technology adopting a concrete mortar preparing device. The concrete mortar preparing device comprises a mixing cylinder, a treatment unit, an additive cylinder and a water feeding unit. The treatment unit is arranged at the upper end of the mixing cylinder. The left end of the mixing cylinder is connected with the water feeding unit through a pipeline. The right end of the treatment unit is connected with the additive cylinder through a pipeline. By designing the pagoda type multi-grade structure of the material mixing device, the manner of feeding sand, stone and cement at the first grade, feeding various additives at the second grade, feeding water at the third grade is adopted, each step of the technology is treated in a separated manner, and then the problem that since residual additives and moisture can conduct a reaction with the sand, stone and cement earlier, the strength of the concrete is lowered is solved. According to the hierarchical multi-grade type concrete mortar preparation material mixing treatment technology, by feeding the mortar at a fixed quantity and then feeding water at a fixed volume, the problem that due to excessively fed water, the strength and viscosity of the concrete are influenced is solved.

Description

technical field [0001] The invention relates to the technical field of construction material preparation, in particular to a layered and multistage concrete mortar preparation and mixing process. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. [0003] The following problems often exist in the process of preparing concrete mortar and mixing materials: 1. The existing equipment often adds raw materials in a mixing drum for mixing and stirring. This process will cause a small amount of additives and moisture to...

AI Technical Summary

Problems solved by technology

[0003] The following problems often exist in the process of preparing concrete mortar and mixing materials: 1. The existing equipment often adds raw materials in a mixing drum for mixing and stirring. This process will cause a small amount of additives and moisture to remain on the inner wall of the mixing drum. As a result, when the concrete mortar is prepared again, the residual additives and moisture will react with the sand and cement first, thereby reducing the strength of the concrete; 2. In the separate preparation of the concrete mortar, there will often be material residues during the re-transportation process, resulting in The material must be less than the amount placed, so that when water is injected, too much water is often injected, which affects the strength and viscosity of the concrete
