Composite modified mortar for air-entrained bricks
The invention discloses composite modified mortar for air-entrained bricks. The mortar is prepared from the following ingredients (by weight): 58% of quartz sand, 11% of fly ash, 4% of glass fiber, 2% of diatomite, 3% of bentonite, 4.5% of quicklime, 9% of cement, 2% of aluminium powder, 4.5% of redispersible latex powder, 1% of a water reducer and 1% of an additive. The production technology is simple, and cost is low. The prepared mortar has good strength, low thermal conductivity and good crack resistance, is energy-saving and environmentally friendly, satisfies needs of constructional engineering and accords with requirements of environmental protection. 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.
