The preparation and properties of steel slag permeable bricks
With the development of sponge city construction,permeable bricks as a new ma-terial are receiving more and more attention.In this study,uncarbonized steel slag was used as coarse and fine aggregate to prepare steel slag permeable bricks,and the effects of target porosity,molding pressure and water-binder ratio on the compressive strength and water permeability of steel slag permeable bricks were studied.The results show that the target porosity,molding pressure and water-binder ratio have significant effects on the properties of steel slag permeable bricks.When the target porosity is 14%,the molding pressure is 9 MPa and the water-binder ratio is 0.28,the optimal mixing ratio is obtained.
