复掺钢渣—石粉对混凝土力学性能的影响

Influence of Mixed Steel Slag and Stone powder on Mechanical Properties of Concrete

该项研究将钢渣替代碎石及石粉替代水泥按不同掺量配制混凝土,对C30混凝土进行力学性能试验。研究结果表明:钢渣掺量为45%时混凝土强度最佳;随着石粉掺量的增加,混凝土的强度呈下降趋势;复掺钢渣及石粉时,钢渣掺量为45%,石粉掺量为5%时强度最佳;钢渣掺量为30%,石粉掺量为10%时,混凝土早期强度增长最快,对急需投入使用的混凝土工程具有一定的指导意义。

Steel slag was used to substitute gravel and stone powder was used to substitute cement, and the mechanical properties of C30 concrete were tested. The results show that: Concrete has the best strength when the steel slag content is 45%.With the increase of stone powder content,the strength of concrete decreases. When the steel slag content is 30% and the stone powder content is 10%,the early strength of concrete increases-most rapidly. It is of guiding significance to the concrete project in urgent need.
