Pervious cement concrete and preparation method thereof

The invention provides pervious cement concrete. The pervious cement concrete is prepared from the following components, in parts by weight: 1400-1500 parts of coarse aggregate, 120-160 parts of fineaggregate, 240-320 parts of cement, 45-66 parts of reinforcer, 8-12 parts of water reducing agent and 55-80 parts of water, wherein the fine aggregate is prepared from fine sand with the particle sizeof 0.075-0.15 mm, fine sand with the particle size of 0.15-0.3 mm and fine sand with the particle size of 0.3-0.6 mm in a mass ratio of 5:2:3. The invention further provides a preparation method andapplication for the pervious cement concrete. The pervious cement concrete has excellent strength and water permeability, the problem that the compressive strength and the water permeability coefficient of the pervious concrete are mutually restricted can be solved, and the foundation is laid for the development of pervious concrete roads. 本发明提供种透水水泥混凝土，原料包括以下重量份的组分：粗骨料1400-1500份，细骨料120-160份，水泥240-320份，增强料45-66份，减水剂8-12份，水5
