摘要
以超高掺量钢渣微粉替换水泥作为胶凝材料,以工业固体废弃物钢渣作为骨料,并掺入玄武岩纤维,开发研制出一种超高掺量钢渣水泥基复合材料。通过试验分析不同掺量钢渣微粉、玄武岩纤维以及不同胶砂比3个维度对其抗压强度变化的影响规律。结果表明,按本次试验的最优配合比设计制作的圆柱体试件,其抗压强度可达到40 MPa以上。在超高掺量钢渣微粉替代水泥作为胶凝材料的范围内,即替代量大于30%情况下,随着钢渣微粉掺量的增加,抗压强度有所下降,但不明显。钢渣作为唯一骨料,其掺量对抗压强度有重要影响,胶砂比从0.31增加到0.44时,强度上升了近60%,达到了40.4 MPa。玄武岩纤维掺量在0~2%范围内,抗压强度随掺量的增加呈现出现先增大后减小的趋势。
The ultra-high volume steel slag powder is used to replace cement as a cementing material,steel slag is used as aggregate,and basalt fiber is mixed to develop a cement-based composite material with ultra-high volume steel slag.The influence of different content of steel slag powder,basalt fiber and changing the mortar ratio on the three dimensions of its compressive strength is analyzed through experiment.The results show that the optimal mix ratio design of this test,the compressive strength of specimens can reach more than40 MPa.In the range where ultra-high volume of steel slag powder replaces cement as a cementing material,namely,when the replacement amount is greater than 30%,as the content of steel slag powder increases,the compressive strength decreases,but not significantly.Steel slag is the only aggregate,and which volume has an important impact on the compressive strength.When the mortar-sand ratio increases from 0.31 to 0.44,it increases by nearly 60% to 40.4 MPa.When the volume of basalt fiber is in the range of 0~2%,the compressive strength increases first and then decrease with the increase of the volume.
