The preparation method of described light-high-strength aerated bricks, is characterized in that comprising the following steps:
(1) by cement, unslaked lime, gypsum, flyash mixing, send into grinding in ball grinder and become 50-100 order particle, then mix with the composition except aluminium powder cream, be that 0.56-0.57 adds water by ratio of water to material, stir, then add aluminium powder cream, stir and obtain slurry;
(2) slurry that (1) step obtains is poured in mould, obtain brick idiosome;
(3) brick idiosome is put into steam-cured room to vacuumize, then in 1.7-1.9 hour, pass into steam equably, make the temperature of steam-cured indoor rise to 170-180 DEG C, pressure reaches 11-13MPa, keeps constant 9-12 hour;
(4) let off steam equably in 1.7-1.9 hour, make the temperature of steam-cured indoor be down to less than 70 DEG C, go out still, place 28-30 days and get final product.
Beneficial effect of the present invention
Aerated bricks of the present invention, by using borsyl tiny balloon, reduces the density of aerated bricks, adds intensity, improve dimensional stability simultaneously, also improve sound insulation and effect of heat insulation; By adding sepiolite cashmere, rock wool, add the breaking tenacity of aerated bricks; By using modification sawdust, reduce dry density and drying shrinkage value, and by the sawdust of used oil process, improve the water tolerance of aerated bricks.
