Novel mortar for air-entrained bricks
The invention discloses novel mortar for air-entrained bricks. The novel mortar is prepared from the following ingredients (by weight): 60% of quartz sand, 10% of fly ash, 4% of zeolite powder, 2% of meerschaum, 0.5% of hydroxyethyl methyl cellulose, 3% of diatomite, 4% of quicklime, 8% of cement, 2% of aluminium powder, 4.5% of redispersible latex powder, 1% of a water reducer and 1% of an additive. The invention has advantages of simple production process and low cost. The prepared mortar has good strength, low heat conductivity and very good anti-crack effect, is energy-saving and environmentally-friendly, satisfies needs of constructional engineering and meets environmental protection requirements. By adding expansive soil into cement for calcination modification, adhesion of cement in the mortar is enhanced. By adding diatomite obtained after technological modification, performance of the mortar is improved, and the mortar has little shrinkage deformation. By using 1 wt% of cellulose ether as an additive, bondability of the ingredients is raised so as to further enhance strength of an air-entrained brick.
