Study on application of steel slag powder from Kunming iron and steel company in concrete
摘要
Abstract
That steel slag of Kunming steel company is used in concrete as active supplementary materials is effective method to realize resource utilization of steel slag. The research is based on potential activity of steel slag powder and mineral composition similar to cement clinker. The slag powders were replaced by steel slag powders to prepare the concrete of C15 ,C20 ,C30 and C40 . Around the effect of steel slag powders on concrete performance,for working performance,mechanical properties and the hydration products of concrete, through the research of liquid, slump loss, exudation rate,compressive strength,tensile strength of concrete mixed steel slag powder and SEM and XRD of net slurry hydration products,the results show that the steel slag powders mixed with slag powders are conductive to improve liquidity,postpone slump loss and reduce lagging bleeding of concrete. The mechanical property meets the design requirements. With mixing the steel slag powders,the kind of hydration products doesn't change. The early hydrate speed of steel slag powders is slow,and the later degree of hydration improves gradually.关键词
