摘要
对用钢渣生产混凝土空心砌块进行了研究。研究结果表明:钢渣的活性较低,若用其生产砌块,必须对其活性进行激发。芒硝对钢渣的活性激发效果较好。用40%32.5级水泥,58%磨细钢渣,2%的芒硝配制的胶凝材料28d抗压强度达22.5MPa,利用该胶凝材料、破碎的钢渣作粗集料、河砂作细集料,制成的空心砌块强度等级达MU10,且耐久性满足GB8239—97要求。
Study has been made on producing concrete hollow block using steel slag, The result of study shows that steel slag has low activity,therefore its activity must be excited if using it to make block. Saltcake has better effect on excitation the activity of steel slag.The compression strength of cementing material at 28 d is up to 22.5 MPa that is prepared with 40% 32.5R cement,58% fine ground steel slag and 2% saltcake.The strength of hollow block is up to MU10 and its durability meets the requirement of GB 8239—97taking the cementing material and broken steel slag as coarse aggregate and river sand as fine aggregate.
