Method for improving compressive strength of aerated recycled concrete

Abstract

The invention relates to a method for improving the compressive strength of aerated recycled concrete. The aerated concrete with the compressive strength improved is completed through cooperation of a bottom plate, a feeding device, a crushing device, an air blowing device and a discharging device. According to the method for improving the compressive strength of the aerated recycled concrete, the problems that the crushing speed of waste glass fibers is low, after the waste glass fibers are crushed, the waste glass fibers are not screened, the waste glass fibers are unqualified after being crushed, existing recycled concrete manufacturing equipment does not adjust the waste glass fibers during blanking after crushing, the proportion of the waste glass fibers added into the concrete is difficult to control, and the compressive strength of the aerated concrete is difficult to improve due to the fact that when the existing recycled concrete manufacturing equipment is used for manufacturing and existing waste glass fiber crushing equipment is used for crushing the waste glass fibers, pressing feeding is not carried out on the waste glass fibers can be solved.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a method for improving the compressive strength of aerated recycled concrete. Background technique [0002] Air-entrained concrete is made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) , pre-curing, cutting, autoclaving, curing and other processes made of lightweight porous silicate products. Because it contains a large number of uniform and fine pores after being aerated, it is named aerated concrete. The production of aerated concrete is rich in raw materials, especially the use of fly ash as a raw material, which can not only comprehensively utilize industrial waste, control environmental pollution, not destroy cultivated land, but also create good social and economic benefits. It is an alternative to traditional solid clay bricks. Ideal wall material. When making air-entrained concrete, waste glass fibers are added to it, so that ...

AI Technical Summary

Problems solved by technology

[0004] (1) When the existing recycled concrete production equipment is producing recycled concrete, the existing waste glass fiber crushing equipment does not pressurize and feed the waste glass fiber when crushing the waste glass fiber, resulting in the waste glass fiber being broken The speed is slow, and after the waste glass fiber is broken, it is not screened, which makes the waste glass fiber broken unqualified;

[0005] (2) The existing recycled concrete production equipment does not adjust the waste glass fiber when it is crushed and unloaded when making recycled concrete, so it is difficult to control the proportion of waste glass fiber added to concrete, and it is difficult to improve the resistance of air-entrained concrete. Compressive strength
