摘要
摘 要:研究了可再分散乳胶粉、硅灰、粗骨料级配对透水混凝土性能的影响。试验结果表明:可再分散乳胶粉、硅灰在透水混凝土中最佳掺量分别为2%、6%;3~5mm粗砂、5~10mm碎石、5~16mm碎石混合骨料透水混凝土抗压强度最高可达37.9MPa,透水系数可满足应用要求。
Abstract: The effect of polymer dispersion powder, silica fume and grade of coarse aggregate on the pervious cement concrete was studied. The results show that: the optimal amount of polymer dispersion powder and silica fume are 2%, 6%, respectively; the 28d compressive strength of pervious cement concrete mixed with 3~5mm sand, 5~10mm gravel and 5~16mm gravel can research 37.9MPa, water permeability can meet the application requirements.
