Embodiment Construction

[0015] A kind of antifreeze aerated brick, it is made by the raw material of following weight kg:

[0016] Fly ash 27, gypsum 9, sodium chloride 0.7, zinc powder 0.15, sodium silicate 1, sodium carbonate 2, sodium bentonite 5, cement 15, magnesium chloride 0.5, river sand 3, Glauber's salt 0.6, sodium tripolyphosphate 2, Peat soil 5, sodium orthosilicate 1, vermiculite powder 5, additive 9;

[0017] The auxiliary agent is prepared from the following raw materials with a weight of kg: iron ore tailings 8, loess 8, steel slag 5, attapulgite 15, gelatin 0.4, glycerol triacetate 2.5, isomeric alcohol polyoxyethylene ether 0.4, Silane coupling agent KH7922, sodium acetate 2, nano silicon dioxide 2;

[0018] The preparation method of described auxiliary agent is:

[0019] Take loess, iron ore tailings and steel slag, mix them evenly, break them, and burn the obtained powder in a flash kiln at 940°C for 3 seconds, then take it out and cool it, mix it with attapulgite, gelatin, tria...

Abstract

The invention discloses an anti-freezing aerated brick which is prepared from the following raw materials in parts by weight: 25 to 30 parts of pulverized fuel ash, 8 to 9 parts of gypsum, 0.5 to 0.7 part of sodium chloride, 0.08 to 0.15 part of zinc powder, 1 to 2 parts of sodium silicate, 2 to 3 parts of sodium carbonate, 4 to 6 parts of sodium bentonite, 15 to 20 parts of cement, 0.4 to 0.8 part of magnesium chloride, 2 to 4 parts of river sand, 0.5 to 1 part of mirabilite, 1 to 3 parts of sodium tripolyphosphate, 3 to 6 parts of peat soil, 1 to 2 parts of sodium orthosilicate, 3 to 5 parts of vermiculite powder and 7 to 9 parts of aiding agent. The anti-freezing aerated brick has the advantages of uniform anti-freezing effect and high anti-freezing degree, and is high in hardness and low in volume weight, thereby being especially suitable for low-temperature construction.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to an antifreeze aerated brick. Background technique [0002] Aerated bricks refer to aerated concrete blocks produced by high-temperature autoclaved equipment. The existing aerated bricks have a single variety and poor performance, which cannot meet the increasing market demand. Contents of the invention [0003] The object of the present invention is to provide an antifreeze aerated brick. [0004] The above purpose is achieved through the following schemes: [0005] An antifreeze aerated brick is characterized in that it is made from the following raw materials in parts by weight: [0006] Fly ash 25-30, gypsum 8-9, sodium chloride 0.5-0.7, zinc powder 0.08-0.15, sodium silicate 1-2, sodium carbonate 2-3, sodium bentonite 4-6, cement 15-20, Magnesium chloride 0.4-0.8, river sand 2-4, Glauber's salt 0.5-1, sodium tripolyphosphate 1-3, peat soil 3-6, sodium orthosilicate 1-2, ver...
