摘　　要：以武钢高炉水淬矿渣为主要原料,试验研究了激发剂种类、水泥掺量、骨料的颗粒级配和掺量,以及不同养护条件等对矿渣免蒸砖力学性能的影响。研究结果表明,利用这种工业废渣制备新型墙体材料切实可行,且当水泥掺量为5%,复合激发剂掺量在4%,骨料掺量为60%,水胶比为0.12时,矿渣免蒸砖的抗压强度达到53.4MPa左右,软化系数达0.94左右。利用优化配合比成型标准砖强度高,干燥收缩小,抗冻性能好达到粉煤灰砖M20级的要求。This paper researches on the effect of the activator, the cement content the aggregate grain, aggregate amount, and curing condition on the mechanics of non-autoclaved brick made of blast furnace water quenching slag. The results show that when the cement mixing content is 5 %, composite activator is at 4 %, the aggregate mixing content is 60 %, and water-binder ratio is 0.12, the compressive strength can reach 53.4 MPa and soften coefficient is about 0.94. The brick has high strength and small drying shrinkage and excellent frost resistance.
