Problems solved by technology

[0003] The traditional bricks used in construction generally use solid clay bricks as sintered ordinary bricks (commonly known as red bricks). Most of these bricks are sintered from cultivated land clay, which seriously damages the cultivated land and causes the loss of a large amount of land resources. At the same time, during its firing process, a large amount of fuel will be wasted and air pollution will be caused.
In addition, the current red bricks have many disadvantages such as heavy weight, poor processing performance, and poor sound insulation performance.

Abstract

The invention relates to an autoclaved aerated concrete building block and a preparation method thereof, in particular to an autoclaved aerated concrete building block containing industrial solid waste and a preparation method thereof. The autoclaved aerated concrete building block containing industrial solid waste comprises, by weight percent, 35%-47% of base material, 35%-39% of magnesium chloride solution, 10%-15% of magnesium oxide, 2%-5% of binder, 2%-3% of industrial hydrogen peroxide, 1%-2% of lanthanide rare earth, and 5%-7% of additive. The autoclaved aerated concrete building block has the advantages of fire prevention, water proofing, moth prevention, lightness, crush resistance, bending resistance, high strength, moss avoidance and the like. The proportion of the materials determines the water proofing and moth prevention. The fire prevention meets the standard (class A) of nonflammable materials. The crush resistance is larger than 53Mpa. The bending resistance is larger than 80Mpa. In addition, the industrial solid waste is effectively utilized, wastes are utilized, environment is protected, and the wastes are turned into wealth.

Description

technical field [0001] The invention relates to an autoclaved aerated concrete block and a preparation method thereof, in particular to an autoclaved aerated concrete block containing industrial solid waste and a preparation method thereof. Background technique [0002] With the development of industrial production, the amount of industrial waste is increasing day by day. Its passive stacking occupies land, pollutes soil, water and air, affects crop growth, and endangers human health. After industrial waste is generated, it must occupy an area and be piled up. The larger the amount of accumulation, the more land will be occupied. The waste is piled up, and the harmful components in it are easy to pollute the land. When pathogenic microorganisms and other harmful substances in polluted soil enter water bodies with natural precipitation, runoff or seepage, they may further endanger human health. Industrial solid waste also disrupts the ecological balance within the soil. So...
