摘　　要：为研究全钢渣集料对透水砖性能的影响,以粗钢渣取代粒径和水灰比为影响因素,开展全钢渣集料透水砖透水系数和抗压强度试验研究。结果表明:全钢渣集料透水砖的透水系数随着粗钢渣取代粒径的增大先增大后减小,随着水灰比的增加逐渐增大;抗压强度与粗钢渣取代粒径成正相关,与水灰比成负相关。在试验基础上,提出全钢渣集料透水砖透水系数和抗压强度的计算式。In order to study the influence of full steel slag aggregate on the performance of pervious brick,the permeation coefficient and compressive strength of the full steel slag aggregate pervious brick are studied by taking the substituted particle diameter of coarse aggregate and water-cement ratio as influencing factors.The results show that the permeation coefficient of the full steel slag aggregate pervious brick first increases and then decreases with the increase of the substituted particle diameter of coarse aggregate,and gradually increases with the increase of the water-cement ratio.The compressive strength is positively correlated with the substituted particle diameter of coarse aggregate and negatively correlated with the water-cement ratio.Based on the experimental research,the equation for the permeation coefficient and compressive strength of full steel slag aggregate pervious brick are proposed.
