Embodiment Construction

[0016] An antifreeze concrete aerated brick, which is made from the following raw materials in parts by weight (kg): fly ash 40, cement 20, wollastonite powder 20, modified straw ash 10, gypsum 4, aluminum powder 0.1, urea 3.3, Oxidized paraffin wax soap 0.03, sugar calcium 2, calcium formate 6, polyethylene wax powder 0.3, calcium carbonate 5, calcium nitrate 0.4, sodium acetate 0.2, appropriate amount of water;

[0017] The preparation method of the modified straw ashes is as follows: 8 parts by weight of dry straw, 2 parts by weight of calcium carbide slag, and 1.5 parts by weight of chaff are mixed and burned at 1300 ° C for 5 hours, and mixed with phosphoric acid equivalent to 2% of the weight of the powder. Trisodium and 1% diethanolamine are stirred evenly, dried and crushed into powder.

[0018] A kind of antifreeze concrete aerated brick,

[0019] (1) Weigh fly ash, cement, and wollastonite powder in parts by weight, then add appropriate amount of water, mix well and...

Abstract

The invention discloses an anti-freeze aerated concrete brick. The anti-freeze aerated concrete brick is prepared from the following raw materials in parts by weight: 35-40 parts of fly ash, 15-20 parts of cement, 15-20 parts of wollastonite powder, 5-10 parts of modified straw ash, 2-4 parts of gypsum, 0.05-0.1 part of aluminum powder, 2-4 parts of urea, 0.01-0.03 part of oxyparaffin soap, 1-2 parts of sugar calcium, 4-6 parts of calcium formate, 0.1-0.5 part of polyethylene wax powder, 4-6 parts of calcium carbonate, 0.2-0.4 part of calcium nitrate, 0.1-0.2 part of sodium acetate and right amount of water.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to an antifreeze concrete aerated brick. 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 antifreeze concrete aerated brick. [0006] The above purpose is achieved through the following schemes: [0007] An antifreeze concrete aerated brick,...
