The invention discloses an aerated
brick with an anti-freezing function. The aerated
brick is characterized by being prepared from the following raw materials in parts by weight: 20-25 parts of lead-
zinc tailing
powder, 17-19 parts of household garbage, 11-14 parts of
lime, 0.2-0.5 part of aluminum
powder, 5-7 parts of
phosphate cement, 10-13 parts of natural yellow sand, 2-4 parts of
potassium sulfate, 1-4 parts of
EDTMP.Na5, 2-5 parts of
ammonium bicarbonate, 0.3-0.6 part of tara gum, 0.2-0.4 part of tamarind gum, 1-3 parts of soda ash, 3-5 parts of chestnut shells, 0.5-0.7 part of
gelatin, 0.1-0.3 part of dried
tangerine peel, 0.3-0.5 part of moxa leaves, 4-6 parts of auxiliaries and a proper volume of water. The prepared aerated
brick disclosed by the invention has good anti-freezing property; through adding proper auxiliaries and foam stabilizer, the
toughness of the aerated brick is improved, and the
permeation resistance is improved; moreover, the
processing process is simple and easy to implement, the production cost can be reduced, the cyclic economy effect of changing the waste into the valuable is realized, and the competitiveness of the product is improved.
