摘要
研究了集灰比、外加剂、增强剂种类和掺量对透水混凝土性能的影响。结果表明：集灰比与透水混凝土孔隙率和透水系数呈正比，与抗压强度呈反比关系；增强剂可显著提高提高透水混凝土抗压强度、孔隙率及透水系数；外加剂对透水系数影响较大，不建议在透水混凝土中使用；不同厂家的增强剂产品对透水混凝土的抗压强度影响较大。
Abstract
The effects of ash aggregate ratio, admixture, reinforcingagent and addition agent on the performance of permeable concrete arestudied.The results show that the ash aggregate ratio is proportionalto porosity and permeability coefficient of permeable concrete, andis inversely proportional to the compression strength.The reinforcingagent can significantly improve the compression strength, porosity andpermeability coefficient of permeable concrete.The admixture has greatinfluence on permeability coefficient and is not recommended to beused in permeable concrete.The reinforcing agent products of differentmanufacturers have great influence on the compression strength ofpermeable concrete.
