透水混凝土是一种环境友好型建筑材料,但强度普遍较低限制了其应用。为配制出强度高于30MPa并满足透水要求的透水混凝土,本试验分别从目标孔隙率、水灰比、砂率和掺合料掺量几个方面研究了这些因素对透水混凝土强度和透水系数的影响,为透水混凝土的应用提供一定的参考。 Permeable concrete is an environmentally friendly building material, but its generally lower strength limits its use. In order to prepare pervious concrete with the strength above 30MPa and meet the requirement of water permeability, the influences of these factors on the strength and water permeability of pervious concrete were studied in this paper from the aspects of target porosity, water-cement ratio, sand rate and admixture content Influence, provide some reference for the application of pervious concrete.
