Autoclaved aerated concrete slab with ultralow heat conductivity coefficient
The invention discloses a production process of autoclaved aerated concrete with an ultralow heat conductivity coefficient. The production process comprises the following steps: proportionally preparing raw materials, adding the raw materials into a stirring tank, carrying out stirring at a high speed of 1400 revolutions per minute, pouring the stirred materials into a mold, carrying out walking and standing successively, opening the mold, performing overturning and cutting, removing a backing material, carrying out steam curing, breaking off a plate, inspecting and warehousing a finished product. A formula for the autoclaved aerated concrete with the ultralow heat conductivity coefficient in the invention comprises, on the basis of 1300 kg (5m<3>) of a total feeding amount, 120 kg of lime, 500 kg of cement, 480 kg of mortar (dry), 200 kg of waste slurry (dry), 2.7 kg of aluminum powder (dry), 200 ml of an admixture 1 and 200 ml of an admixture 2, wherein a water cement ratio is 0.82.
本发明公开了超低导热系数蒸压加气混凝土的生产工艺为将上述原料按比例配制后，加入到搅拌罐中进行高速搅拌，转速为每分钟1400转，将搅拌好的物料浇注到模具中，行走静停，开模，翻转切割，底料去除，蒸养，掰板，成品检验入库。本发明超低导热系数蒸压加气混凝土，其配方是总投料量：1300公斤(5立方)石灰：120公斤，水泥500公斤，砂浆(干)480公斤，废浆(干)200公斤，铝粉(干)2.7公斤，水灰比：0.82，外加剂1：200ml，外加剂2：200ml。
