一种再生粉体蒸压砖及其制备方法
摘要：
本发明公开了一种再生粉体蒸压砖及其制备方法，该再生粉体蒸压砖包含如下成分及含量：0～15重量％水泥；50～70重量％再生砂；15～30重量％再生粉体；0～15重量％生石灰粉；余量为水，且水料比为0.15～0.35。将上述比例的水泥、再生砂、再生粉体、生石灰粉、水加入搅拌机搅拌2～4min，出料后运至压砖机，于15～20Mpa压制成型；经静停养护2～3h后送入蒸压釜蒸养：温度为175～230℃，压力为0.8～1.3Mpa，搅拌2～4min，升温1～3h，恒温3～9h，降温1～3h即可获得所述再生粉体蒸压砖。本发明的再生粉体蒸压砖，质量轻，容重为1800-1980kg/m3，强度为10MPa-20MPa，保温隔热性能良好，耐高温，耐化学腐蚀，耐久性能良好，能用于墙体砌筑。
摘要（英）：

The invention discloses a renewable powder autoclaved brick and a manufacture method thereof. The renewable powder autoclaved brick contains the following components: 0-15wt% of cement, 50-70wt% of reclaimed sand, 15-30wt% of renewable powder, 0-15wt% of quicklime powder and the balance of water, wherein the ratio of water to the materials is 0.15-0.35. The manufacture method comprises the following steps of: adding cement, reclaimed sand, renewable powder, quicklime powder and water according to the ratio to a stirrer, stirring for 2-4 minutes, discharging, conveying to a brick pressing machine, and pressing for shaping at the pressure of 15-20 MPa; and standing and maintaining for 2-3 hours, conveying to an autoclave for curing at the temperature of 175-230 DEG C and the pressure of 0.8-1.3 MPa, stirring time of 2-4 minutes, heating time of 1-3 hours, heat insulation time of 3-9 hours and cooling time of 1-3 hours to obtain the renewable powder autoclaved brick finally. The renewable powder autoclaved brick provided by the invention has the advantages of light weight, volume weight of 1800-1980 kg/m<3>, strength of 10-20MPa, good thermal insulation property, high-temperature resistance, chemical corrosion resistance and excellent durability, and can be used for wall building.
