| 摘 要： | 针对重庆地区透水水泥混凝土配比设计与技术性能进行研究,结果发现:1)水胶比为0. 28~0. 32且空隙率在16%~24%时,混凝土具有良好的透水性能、抗压性能及抗弯拉性能,能满足重庆地区城市道路施工及海绵城市建设的相关要求;2)设计的透水混凝土有效孔隙率与总孔隙率呈正相关,抗压强度和抗弯拉强度则与孔隙率呈负相关,透水系数与孔隙率也呈负相关。

| Abstract: | Mix proportion design and technical performance of pervious cement concrete for Chongqing area are studied in this paper. The results show that: 1) when the water cement ratio is 0. 28-0. 32 and the void ratio is 16%-24%,the concrete has good water permeability,compression resistance and bending tensile resistance,which can meet the requirements of urban road construction and sponge city construction in Chongqing;2) There is a positive correlation between the total porosity and the effective void ratio of the designed permeable concrete,a negative correlation between the compressive strength and flexural strength,and a negative correlation between the permeability coefficient and porosity. |
