Abstract

The invention relates to an oil-resistant aerated concrete block. The oil-resistant aerated concrete block is prepared by the following raw materials by weight: 0.04-0.06 part of aluminum powder, 0.002-0.004 part of peregal, 0.1-0.2 part of polypropylene fibers, 2-4 parts of calcium lignosulphonate, 6-8 parts of desulphurization gypsum, 0.01-0.02 part of sulfur trioxide, 0.02-0.03 part of sodium gluconate, 0.4-0.8 part of an FDN water reducing agent, 2-3 parts of calcium stearate, 10-14 parts of kiln dust, 2-5 parts of calcium sulfate, 2-4 parts of aluminum sulfate, 2-4 parts of zirconia, 10-15 parts of fly ash, 8-12 parts of cement, 0.0001-0.0004 part of barium petroleum sulfonate, 0.31-0.55 part of sodium acetate and 3-5 parts of silicon dioxide.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to an oil-resistant aerated concrete block. Background technique [0002] Aerated bricks are aerated concrete blocks produced by high-temperature autoclaved equipment. "Aerated brick" can be understood as a simplified or a general name. The range of products it covers should be larger, that is, bricks produced by various other processes including autoclaving. [0003] In the past, the wall materials used in the construction market were mainly red bricks, but now many advanced areas have completely banned the use of red bricks. [0004] The existing technology of aerated bricks is slow to develop and cannot meet the diversified market demands. Contents of the invention [0005] The object of the present invention is to provide an oil-resistant aerated concrete block. [0006] The above purpose is achieved through the following schemes: [0007] An oil-resistant aerated concrete b...
