This experiment uses the steel slag powder to instead of part of the cement;focuses on analysis of the influence of steel slag powder to compressive strength and the early crack resistance of concrete.The results show that,the steel slag powder can be made of high strength high performance concrete;the steel slag powder content in the range of 0-30%,the 28 d compressive strength of concrete more than 50 MPa;At the same water-cement ratio the incorporation of slag powder is conducive to enhancing anti-cracking performance of concrete and with the increase in volume crack resistance of high performance concrete more outstanding;In the same water-cement ratio,slag powder mixed with non-doped specimen specimen comparison and found that the former is the mixing of slag powder,The initial cracking time of concrete appear appropriately to postpone.Fractal geometry analysis shows that steel slag powder mixed with concrete can improve its crack resistance.
