摘　　要：根据目前国内外对透水性混凝土的研究现状,利用无熟料高炉矿渣水泥(简称NSC)配制透水性混凝土,并进行了透水系数、孔隙率、pH、抗压强度等性能测试。结果表明:其抗压强度可达普通混凝土强度等级的C30以上,满足JC/T446—2000《混凝土路面砖》性能;透水系数≥17.3 mm/s;孔隙率≥27.3%;pH=8.6,有效地解决了透水性混凝土抗压强度低、渗透水强碱化的技术难题。According to the current research on permeability concrete home and abroad, No-clinker Blast Furnace Slag Cement（NSC） is used to configure permeability concrete ,and tests on permeability coefficient, gap rate, pH and compression strength carried out.The result shows that compressive strength ofit is higher than C30 of common concrete, which not only accord with Road Surface Brick of Concrete （JC/T 446-2000）, including permeability coefficient t〉 17.3 mrrds, gap rate ≥ 27.3%, pH=8.6, but also effectively solves the problem that compressive strength of permeability concrete of low and permeability water of strong alkalization.
