摘　　要：为适应海绵城市建设发展的需要,着力改善道路交通与生态环境,尝试选取不同的碎砖骨料掺量和减水剂掺量作为配合比设计参数,制备碎砖骨料透水混凝土,并对其物理力学性能进行测试分析。结果表明,随着碎砖骨料掺量的增加,碎砖骨料透水混凝土的透水系数增大,软化系数和7、28 d抗压强度下降;随着减水剂掺量的增加,碎砖骨料透水混凝土的透水系数减小,软化系数和7、28 d抗压强度都呈先升高后降低的趋势。In order to realize the construction of Sponge City and contribute more to improve the ecological environment and road traffic conditions,the crushed brick pervious concrete was made with different crushed brick and water reducing admixture amounts,the physical properties and mechanical behaviors of the pervious concrete were also tested and analyzed.Results show that with the increasing of crushed brick,the permeability coefficient of the pervious concrete increases while the softening coefficient and the 7 and 28 d compressive strength of the pervious concrete decrease.With the increasing of water reducing admixture,the permeability coefficient of the pervious concrete decreases while the softening coefficient and the 7 and 28 d compressive strength of the pervious concrete all increase first and then decrease.
