Abstract：Through the pre-treatment of hot-steaming steel slag,such as grading and aging,converter steel slag is used as coarse aggregate to replace crushed stone,and cast steel slag is used as fine aggregate to replace natural river sand to prepare concrete pavement bricks,and to study the effect of the replacement rate of steel slag aggregate on its physical and mechanical properties.The results show that:after pretreatment,the fine aggregate of cast surplus steel slag can replace 100%of natural river sand,and improve the early and late compressive strength as well as abrasion resistance and frost resistance of concrete pavement bricks,and after pretreatment,the coarse aggregate of converter steel slag can replace a small amount of natural crushed stone,and when its substitution rate is 40%,the length of grinding pit of concrete pavement bricks can be reduced by 10.3 mm compared with that of natural crushed stone,and the abrasion resistance can be improved by 40.7%.The abrasion resistance is improved by 40.7%.
