摘　　要：为研究透水混凝土强度及透水性能的影响因素,该文探索水胶比、砂率、粉煤灰和硅灰掺量对透水混凝土的抗压强度和透水性能的影响,并制备出高强、高透水性能的透水混凝土;为探究废弃橡胶应用于透水混凝土材料的可行性,该文探索不同橡胶粉掺量对透水混凝土抗压强度和透水性能的影响。试验结果表明:当水胶比为0.22、砂率为6%、矿物掺合料掺量为20%时,可制备出高强高渗透性的透水混凝土;当橡胶粉替代掺量为25%时,可提高透水混凝土抗压强度,且对透水性能无较大影响。To study the influencing factors of the strength and permeability of permeable concrete,this paper explores the effects of water-to-binder ratio,sand ratio,fly ash and silica fume content on the compressive strength and water permeability coefficient of permeable concrete,and prepares permeable concrete with high compressive strength and high permeability.To explore the feasibility of using waste rubber in permeable concrete,the influence of different rubber powder content on the compressive strength and water permeability of permeable concrete was explored.The test results show that:when the water-binder ratio is 0.22,the sand ratio is 6%,the content of mineral admixture is 20%,high-strength and high-permeability permeable concrete can be prepared.When the rubber powder substitution content is 25%,the compressive strength of the permeable concrete can be improved,and it has no major influence on the water permeability.
