摘　　要：为提供透水混凝土的路面强度和耐久性能,研究了外加剂和掺合料对透水混凝土强度和耐久性能的影响,采用CT扫描技术,分析了不同材料对透水混凝土孔隙特征的影响,并总结孔隙特征与强度、抗剥落性能的关系。结果表明:不同材料会影响透水混凝土的孔隙特征,提高透水混凝土的强度,但均未见显著的相关性;不同材料的掺入可以提高透水混凝土的抗剥落性能,但提高的幅度不同,孔隙率对抗剥落性能有一定的影响,而孔隙数量和等效孔径基本无影响。To provide the strength and durability of pervious concrete pavement,the influence of additives and admixtures on the strength and durability of pervious concrete was studied.CT scanning technology was used to analyze the influence of different materials on the pore characteristics of pervious concrete,and the relationship between pore characteristics,strength,and anti-stripping performance was summarized.The results show that different materials can affect the pore characteristics of pervious concrete and improve its strength,but no significant correlation is observed.The addition of different materials can improve the anti-stripping performance of pervious concrete,but the degree of improvement varies.Porosity has a certain impact on the anti-stripping performance,while the number of pores and equivalent pore size have little effect.
