Problems solved by technology

In its formula, fatty acid soap and acacia powder are added to increase the stability of the slurry. However, the addition of fatty acid soap and acacia powder will inevitably lead to an increase in production cost. In addition, it is necessary to mix fly ash and desulfurization The mixed grinding of gypsum powder makes the preparation steps more cumbersome and further increases the cost
[0006] The application publication number is CN103964797A, and the application publication date is 2014-8-6 for autoclaved aerated concrete bricks, which need to mix phosphorus slag and silica sand and then carry out subsequent steps, which makes the preparation steps more cumbersome and the production cost is higher

Abstract

The invention relates to an autoclaved aerated concrete brick. The autoclaved aerated concrete brick is prepared from, by weight, 60%-80% of coal ash and / or sand, 10%-20% of waste, 0.5%-10% of cement, 5%-15% of lime, 1%-10% of gypsum and 0.01%-0.2% of aluminum powder. By means of improving the formulation and optimizing specific process parameters in a preparation method, no fatting acid soap or gleditsia sinensis needs to be added; the use amount of the cement and the aluminum powder is further reduced, environmental pollution is reduced, and raw material cost is reduced. In addition, the coal ash and the gypsum do not need to be mixed and ground, preparation steps are reduced, and production cost is further reduced. The waste is used as part of the raw materials, the waste can be recycled, and raw material cost is reduced. In addition, all performance indexes of the prepared autoclaved aerated concrete brick are qualified.

Description

technical field [0001] The invention relates to an autoclaved aerated concrete brick and a preparation method thereof. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from combustion power plants. , the discharge of fly ash from coal-fired power plants is increasing year by year; if a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; Biohazard. [0003] The disposal cost of fly ash is high, and the investment in new waste ash dams is large. With the increasing improvement of national groundwater pollution prevention and control and solid waste pollution prevention and control regulations, the environmental protection requirements for new waste ash dams will be stricter in the future, and the investment in new waste ash dams The cost will be much higher than the existing waste ash dam, site selection will be more difficult, maintenance ...
