摘 要:研究了钢渣粉替代部分水泥对超高性能混凝土(UHPC)性能的影响,验证了利用钢渣粉部分替代水泥制备生态型UHPC的可行性。结果表明:随着钢渣粉替代量的增加,UHPC的工作性得到改善;当钢渣粉替代量为200 kg/m3时,UHPC的密实度达到最大,且此时UHPC的抗压强度和抗氯离子渗透性能仍保持较好水平;随着钢渣粉替代量的增加,UHPC对生态环境的负面影响逐渐变小。
Abstract: The effect of steel slag powder replacing part of cement on the performance of ultra-high performance concrete(UHPC) was studied, and the feasibility of preparing ecological UHPC by partially replacing cement with steel slag powder was verified. The results show that with the increase of steel slag powder replacement amount, the workability of UHPC is improved. When the replacement amount of steel slag powder is 200 kg/m3, the compactness of UHPC reaches the maximum, and the compressive strength and chloride ion permeability of UHPC still maintain a good level. The negative impact of UHPC on the ecological environment gradually decreases with the increase of steel slag powder replacement amount.
