为研究废陶粒透水混凝土的配比对透水混凝土性能的影响,通过正交试验分析陶粒掺量、颗粒级配及水灰比对透水混凝土孔隙率、抗压强度、透水性能的影响。结果表明:随着水灰比及掺入陶粒大粒径质量占比量的增大,透水混凝土的抗压强度降低,透水系数增大。试验最优配比方案为:陶粒掺量40%,陶粒级配为m_((5~10 mm))∶m_((10~15 mm))=6∶4,水灰比为0.3,该组合下透水混凝土抗压强度为25.2 MPa,透水系数为3.9 mm/s。

In order to study effect of the incorporation ratio with waste ceramsite on characteristics of the pervious concrete,the effects of cera-msite content,particle size distribution and water-cement ratio on porosity,compressive strength and per-meability of pervious concrete were analyzed by orthogonal tests.The results show that the compressive strength of pervious concrete decreases and the water permeability coefficient increases with the increase of water-cement ratio and the mass proportion of large particle size mixed with waste ceramsite.Th...
