单掺砂状钢渣混凝土的抗压强度试验研究

摘要

The steel slag in sand shape replaces the fine aggregate in equivalent quantity to mix the steel slag concrete.Aiming at the strength of the slag concrete, tests are performed based on the impact factors such as water-cementitious ratio, quantity of steel slag mixed, etc.The tests present that the optimum quantity of steel slag mixed in concrete is 30%.Furthermore, the strength (above 28 d) of the concrete with corresponding optimum quantity of the steel slag mixed, while the water-cementitious ratio is fixed, is close to or higher than that of the ordinary concrete.%使用砂状钢渣等量代替混凝土中细集料配制钢渣混凝土，针对钢渣混凝土的强度指标，围绕水胶比、钢渣掺量等影响因素进行试验研究。试验结果表明：砂状钢渣在混凝土中的最优掺量是30％，并且在水胶比一定时，相应最优掺量钢渣混凝土28 d以上龄期强度均接近或超过普通混凝土。
