| 摘 要： | 通过理论计算和试验分析,揭示骨灰比、砂率和水灰比对再生骨料透水混凝土力学性能和透水系数的影响规律.采用功效系数法得出再生骨料透水混凝土配合比控制参数,即骨灰比为3.5,砂率为15%,水灰比为0.34.通过优选配合比参数,得到具有良好透水性能的再生骨料透水混凝土路面砖,其抗压强度可达到20MPa以上;降低透水能力的要求,则其强度可以满足JC/T 466-2000混凝土路面砖标准的要求.

| Abstract: | By theoretical calculation and experimental investigation,the author systematically revealed the effects of aggregate to cement ratio,sand to aggregate ratio and water to cement ratio on mechanical performance and pervious coefficient of recycled aggregate concrete.By adopting the method of effect coefficient,the control parameters of mix ratios were obtained as follows: ratio of aggregate to cement is 3.5,ratio of sand to aggregate is 0.15 and ratio of water to cement is 0.35.By optimizing the parameters of mix proportion,the compressive strength of pervious bricks made of the recycled aggregate concrete with good pervious performance,is over 20 MPa.When lowering the requirement of water permeability,the pervious bricks would meet the requirement of concrete pavement brick standard(JC/T 466-2000). |
