Autoclaved curing production process of aerated concrete blocks

Abstract

The invention provides an autoclaved curing production process of aerated concrete blocks. The autoclaved curing aerated concrete block production process comprises the following steps that (a) mixedslurry is made from artificial quartz stone wastes, sand, lime, cement, gypsum and water; (b) steam is introduced into the mixed slurry, so that the temperature of the mixed slurry rises to 40-45 DEGC, stirring is performed for 3-4 minutes, then a foaming agent is added, and stirring is performed for less than or equal to 40 seconds to prepare casting slurry; (c) after the casting slurry is poured into a mold, and aerating initial setting is performed to prepare a green body; and (d) demolding, cutting and the autoclaved curing are performed on the green body to obtain aerated concrete blockfinished products. The production process has the characteristics that artificial quartz stone waste resources are effectively recycled, the environment is facilitated, the production period is short,and the quality of finished products is high.

Description

technical field [0001] The invention relates to an autoclaved curing aerated concrete block production process, which belongs to the field of building material processing. Background technique [0002] At present, most of the wall materials used in buildings are still brick masonry, and clay bricks account for more than 80% of the total wall materials. In order to produce building bricks every year, not only a large amount of cultivated land needs to be occupied, but if things go on like this, the cost of brick making Soil sources are increasingly depleted, the ecological balance is destroyed, and the area of ​​cultivated land decreases sharply. The resulting chain reaction is extremely harmful. The aerated concrete block is a new type of energy-saving wall material in the first category. It has excellent thermal insulation and anti-seismic performance. It gradually replaces clay bricks with excellent performance and continuously expands the application field. However, the ...

AI Technical Summary

Problems solved by technology

However, the existing aerated concrete blocks use quartz sand as the main raw material, which consumes a lot of resources and is still easy to cause resource depletion

The condition setting of the conventional maintenance of the existing air-entrained concrete blocks is not optimized enough, and the maintenance period is long, which affects the production efficiency

[0003] Represented by quartz stone production enterprises, the amount of artificial quartz stone waste discharged every year is very alarming, but there is still a lack of reasonable and effective recycling methods, so that the recyclable substances in artificial quartz stone waste are mainly disposed of in the traditional way of landfill. Disposal wastes renewable resources and has a negative impact on the environment
