摘　　要：为解决河湖淤泥对环境带来的不利影响,开展了利用河湖淤泥制备透水路面砖的研究.选取广州市具有代表性的河湖淤泥,对淤泥基本物化性质进行了分析,并以河湖淤泥替代部分混凝土骨料调配基层材料,再分别以透水砖的淤泥掺和量0.0%~30.0%、水灰比0.30~0.38和胶骨比1∶3.0~1∶4.5为变量进行试验,对透水砖的抗折、透水系数等性能进行测试,研究利用河湖淤泥制备透水路面砖的可行性及相应参数配比,得到最佳基础配比为胶骨比1∶3.0、淤泥掺和量10.0%和水灰比0.32,为实现河湖淤泥的资源化利用提供了参考.In order to solve the adverse impact of river and lake sludge on the environment,a study was carried out on preparing of permeable pavement bricks with river and lake sludge.The representative river and lake sludge in Guangzhou was selected,and the basic physical and chemical properties of the sludge were analyzed.The river and lake sludge was used to replace part of the concrete aggregate to prepare the base material.Then the tests were carried out with sludge content 0.0%~30.0%,the water cement ratio 0.30~0.38,and the glue bone ratio 1∶3.0~1∶4.5.The flexural resistance,permeability coefficient of permeable were determined bricks.Based on the analysis of the experimental data,the feasibility of preparing permeable pavement bricks by using river and lake sludge and the corresponding mix ratio were studied.The optimum basic ratio was obtained with glue-bone ratio 1∶3.0,sludge mixing amount 10.0%,water-cement ratio 0.32,which provided a reference for the resource utilization of river and lake sludge.
