Zusammenfassung:The invention discloses a preparation and using method of steam-curing alkali-activated cement. A small amount of industrial alkali and potassium sodium aluminosilicate and limestone are mixed and ground to be calcinated under the temperature of 1,250-1,300 DEG C and quenched to obtain a clinker, the clinker is ground into powder and evenly mixed into 3.0-12.0% of sodium silicate with the modulusbeing 1.0-3.2 to obtain cement, the cement is steamed and cured under the temperature of 50-80 DEG C for 8-24 h after being mixed with water to be uniform, and a high-intensity hardening body is obtained. The prepared cement has the advantages that hardening is rapid, the strength is high, raw materials are wide, the cost is low, consumption is low, low-carbon emission is achieved, and the performance is stable and easy to control, and the method is particularly suitable for preparing prefabricated parts. 本发明公开了一种蒸养碱激发水泥的制备和使用方法,由少量工业碱与硅铝酸钾钠及石灰石混合粉磨后于1250~1300℃煅烧急冷得到熟料,将熟料磨细成粉后均匀混入模数为1.0~3.2的钠水玻璃3.0~12.0%即得水泥,水泥加水混匀后在
