Autoclaved sand-lime brick and preparation method thereof
The invention provides an autoclaved sand-lime brick and a preparation method thereof, and belongs to the technical field of building materials.The preparation method comprises the steps that 20-25 parts by weight of tailing sand powder, 30-35 parts by weight of stone powder, 3-5 parts by weight of desulfurized gypsum powder, 15-20 parts by weight of lime powder, 10-14 parts by weight of steel slag powder, 3-5 parts by weight of coal cinder powder, 3-5 parts by weight of converter slag powder and 2-3 parts by weight of superfine sand powder are taken as ash materials; the autoclaved sand-lime brick is prepared by sequentially carrying out mixing, stirring, pouring molding, demolding, pre-curing and carbon dioxide curing on the autoclaved sand-lime brick serving as a foaming material and 0.3-0.8 part by weight of aluminum powder serving as a foaming material. The autoclaved sand-lime brick prepared by the invention has good compressive strength, fire resistance, heat insulation and sound insulation.
本发明提供一种蒸压灰砂砖及其制备方法，属于建筑材料技术领域，所述制备方法是取20～25重量份尾矿砂粉、30～35重量份石粉、3～5重量份脱硫石膏粉、15～20重量份石灰粉、10～14重量份钢渣粉、3～5重量份煤渣粉、3～5重量份转炉渣粉和2～3重量份超细砂粉作为灰料，0.3～0.8重量份铝粉作为发气材料，依次经混合搅拌、浇筑成型、脱模与预养护和二氧化碳养护，制得所述蒸压灰砂砖。本发明制备的蒸压灰砂砖具有良好的抗压强度、耐火性能、隔热性和隔音性。
