Superfine silica sand tailing powder autoclaved aerated concrete and preparation method thereof
The invention relates to the field of aerated concrete raw materials, in particular to superfine silica sand tailing powder autoclaved aerated concrete and a preparation method thereof. The superfinesilica sand tailing powder autoclaved aerated concrete comprises superfine silica sand tailing powder with 180-mesh screen residue of less than 3%. The preparation method comprises the following steps: carrying out wet grinding on ultrafine silica sand tailing powder, river sand and aerated concrete crushed waste to prepare slurry, adding quick lime, cement and desulfurized gypsum into the slurry,and carrying out burdening and pouring. The superfine silica sand tailing powder autoclaved aerated concrete prepared by the preparation method is sufficient in chemical reaction, surface powder is not likely to be generated, the strength is good, and the product is not likely to crack.
本发明涉及加气混凝土原料领域，具体而言，涉及超细硅砂尾矿粉蒸压加气混凝土及其制备方法；本发明的超细硅砂尾矿粉蒸压加气混凝土包括：180目筛余量在3％以下的超细硅砂尾矿粉；本发明的制备方法包括：将超细硅砂尾矿粉、河砂和加气混凝土破碎废料湿磨制成浆料，在浆料中混入生石灰、水泥和脱硫石膏，配料浇注。本发明的超细硅砂尾矿粉蒸压加气混凝土的制备方法制备的超细硅砂尾矿粉蒸压加气混凝土化学反应充分不容易产生表面粉末，强度佳，产品不容易开裂。
