摘   要：采用选择性自磨及分选方法，将城市建筑混合垃圾中强度不同的物料分选出来，以其中强度较高的物料破碎分级后作透水混凝土骨料，在混凝土外加剂种类及用量、水灰比一定时，研究了骨料级配、水泥用量等对透水混凝土的连续孔隙率、透水系数、抗压、抗折强度等性能的影响。结果表明，骨料级配及水泥用量对其性能均有影响。当骨料级配为9.5～4.75mm占64.8%、4.75～2.36mm占16.2%，水泥用量为18％时，试件的孔隙率、透水系数、抗压抗折强度均达到了CJJ/T 135—2009《透水水泥混凝土路面技术规程》的指标要求。

Abstract: The methods of selective self-grinding and separation are used to seperate the materials with different strength from the construction waste. The material with a higher strength is used as aggregate components of water permeable cement-concrete after crushing and size fractionation. The influence of aggregate grading, cement dosage, etc. on the continuous porosity, permeability coefficient, compressive strength and flexural strength of permeable cement concrete are studied at the given quantity of a concrete additives and water to cement ratio.In the definite prerequisite of concrete admixture types and the cement ratio, the effects of aggregate gradation and cement dosage on the continuous porosity, permeability coefficient, compressive strength and flexural strength of permeable cement concrete are studied. The results show that aggregate gragradingdation and cement dosage have effect on the performance of the properties of this concrete. When the concrete is made of two particle sizes of aggregate 64.8% of 9.5～4.75mm, 16.2% of 4.75～2.36mm aggregate and 18% cement, gradation are 9.5～4.75mm and  4.75～2.36mm, and account for 64.8% and 16.2% of the total components with remaining cement, and the cement dosage is 18%, the porosity, permeability coefficient and compressive strength of the specimen can meet the needs criterion of the CJJ/T 135—2009 Permeable Cement Concrete Pavement Technical Code.
