Abstract
The application of steel slag in concrete can be improved by using hot-mugging process and steel slag powder after grinding,in the test,the steel slag powder and cement were mixed with different proportions of slag powder in concrete to carry out the experimental research.The influence of steel slag powder content on the working performance and mechanical properties of concrete was studied.The test results show that using steel slag to replace the slag powder in concrete can effectively reduce the water consumption of concrete and improve the cohesion of concrete,but it can prolong the setting time and decrease the compressive strength of concrete in 28 d,but after 90 d,the strength of steel slag powder increases faster than that of the reference concrete,and the appropriate content of steel slag powder in concrete is less than 50 kg.关键词
