苏联研究了用渣碱胶凝材料代替波特兰水泥拌制混凝土和砂浆。渣碱胶凝材料是将磨细的粒化高炉矿渣、钢渣或其它废渣与碱金属水溶液一起拌合而制得的。可利用工业产品,如碱、可溶性碱硅酸盐、含碱废料等作碱金属化合物。混凝土混合物组分按一定顺序加入强制式叶片搅拌机;砂、磨细的渣、碎石。碱液在搅 The Soviet Union studied the use of slag cementitious materials instead of Portland cement to mix concrete and mortar. The slag alkaline cementitious material is prepared by mixing ground granulated blast furnace slag, steel slag or other waste residue with an aqueous alkali metal solution. Industrial products such as alkalis, soluble alkali silicates, alkali-containing wastes, etc. can be used as alkali metal compounds. The components of the concrete mixture are added to the forced blade mixer in a certain order; sand, ground slag, and gravel. Lye is stirring
