Aerated concrete block prepared from single calcium material and preparation method of aerated concrete block

Abstract

The invention relates to an aerated concrete block prepared from a single calcium material and a preparation method of the aerated concrete block. The aerated concrete block is prepared from raw materials in percentage by weight as follows: 80%-82% of quartz sand, 10%-16% of cement, 2%-5% of flue gas desulfurization gypsum, 0.04%-0.05% of aluminum paste, 0.02%-0.03% of an admixture and the balanceof waste. According to the aerated concrete block prepared from the single calcium material cement, product quality is improved greatly while comprehensive utilization of resources is realized, production cost is reduced, the environmental requirements are met, the product is good in appearance quality, and the aerated concrete block integrates high quality, energy saving and waste using.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an aerated concrete block produced from a single calcareous material and a preparation method thereof. Background technique [0002] With the continuous increase in the promotion of new wall materials in my country, aerated concrete blocks are widely used in industrial and civil buildings, the production process of aerated concrete blocks is also constantly innovating, and product performance and technical indicators have been continuously optimized. . At present, the existing aerated concrete block manufacturers mainly produce two types of aerated blocks: cement-lime-fly ash and cement-lime-quartz sand. However, as lime resources become increasingly tense, prices continue to rise , poor quality and other problems, it is imminent to replace lime with cement to produce aerated concrete blocks, but the production of pure cement aerated concrete blocks on the ...

Problems solved by technology

At present, the existing aerated concrete block manufacturers mainly produce two types of aerated blocks: cement-lime-fly ash and cement-lime-quartz sand. However, as lime resources become increasingly tense, prices continue to rise , poor quality and other problems, it is imminent to replace lime with cement to produce aerated concrete blocks, but the production of pure cement aerated concrete blocks on the basis of existing technology is prone to problems such as brittle products and flipping cracks during cutting, so It is of great significance to produce aerated concrete blocks that integrate high quality, energy saving and waste utilization
