研究了钢渣对水泥-高效减水剂体系的相容性和混凝土和易性的影响。结果表明,不同钢渣对浆体流动性和混凝土和易性的影响存在差异。钢渣在改善混凝土和易性方面不如矿渣。部分钢渣对水泥-高效减水剂体系的配伍性有负面影响,加速了浆体的流动性损失,但在饱和掺量中加入减水剂可以减弱这种负面影响。掺入适量的高效减水剂可使钢渣混凝土获得良好的和易性。
The influences of steel slag on the compatibility of cement-superplasicizer system and workability of concrete were investigated in this study. Results show that there are differences among the effects of different steel slags on the fluidity of paste and workability of concrete. Steel slag is not so good as GGBS in improving the workability of concrete. Some steel slags have negative effects on the compatibility of cement-superplasicizer system by accelerating the fluidity loss of paste, but the negative effects can be weakened by adding superplasiticizer content to the saturation dosage. Concrete containing steel slag can get good workability by adding proper superplasiticizer amount.
