摘要
Abstract
In order to determine the safe dosage of steel slag powder used as mineral admixture in concrete,this paper tested the different dosage of steel slag powder instead of cement in the mix ratio of C40 concrete,and studied the influence of steel slag powder dosage on the compressive strength and volume stability of C40 concrete.The results show that:The compressive strength of C40 concrete will decrease significantly with the increase of steel slag powder content,and the loss rate of compressive strength after boiling of concrete core sample will be increased.However,when the steel slag powder content is less than 30%,the influence on the compressive strength of concrete is small.Moreover,it meets the corresponding requirements in the testing method of the influence of f-CaO on concrete quality in GB/T 50344(Technical Standard for Testing Building Structures).关键词
