钢铁渣粉是一种新型的固体废弃物综合利用的产品,作混凝土掺合料有利于改善混凝土的工作性,其配制的混凝土后期强度高。试验主要研究了掺钢铁渣粉混凝土的干缩以及通过高温养护研究其体积安定性,并与纯水泥混凝土、掺矿渣粉混凝土和双掺矿渣粉、粉煤灰混凝土作对比,试验结果表明,掺钢铁渣粉的混凝土干缩值低于掺其他掺合料混凝土的干缩值,并且对混凝土安定性没有影响。
Steel slag is a new type of solid waste comprehensive utilization of products, as a concrete admixture is conducive to improving the workability of concrete, the preparation of concrete with high late strength. The experiment mainly studied the shrinkage of steel slag-doped concrete and its volume stability by high-temperature curing. Compared with pure cement concrete, slag-doped concrete and double-mixed slag powder and fly ash concrete, the experimental results show that, Steel slag powder concrete shrinkage value is lower than other admixture concrete shrinkage shrinkage value, and has no effect on the stability of concrete.
