摘要
通过对影响透水水泥混凝土性能分析,选择水胶比、集胶比、骨料级配和硅灰掺量四个因素三水平。用正交设计的方法,找出影响透水水泥混凝土的透水系数、抗压强度和弯拉强度最佳试验条件,为透水水泥混凝土配合比设计提供思路和方法。
Through the analysis on the permeable cement concrete performance, selects water-binder ratio, aggregate-cement ratio, aggregate gradation, quantity of silica fume, four factors and three levels. Using orthogonal design method, find out the influence to permeable cement concrete permeability coefficient, compressive strength and flexural strength of the optimal experimental condition, to provide ideas and methods for permeable cement concrete mix ratio design.
