钢渣透水砖的制备与性能研究

The preparation and properties of steel slag permeable bricks

随着海绵城市建设的兴起,透水砖作为新兴材料,正受到越来越多的关注。采用未碳化的钢渣作为粗、细骨料制备钢渣透水砖,研究目标孔隙率、成型压力以及水胶比对钢渣透水砖抗压强度及透水性能的影响。研究结果表明:目标孔隙率、成型压力以及水胶比对钢渣透水砖性能影响显著,当目标孔隙率为14%,成型压力为9 MPa,水胶比为0.28为最优配合比。

With the development of sponge city construction,permeable bricks as a new material 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.
