The invention provides pervious concrete and a preparation method thereof. The pervious concrete is prepared from, in parts by weight, 200-300 parts of cement, 30-80 parts of mineral powder, 30-80 parts of fly ash, 1400-1700 parts of gravel, 1-5 parts of rubber powder, 0.5-5 parts of cellulose and cellulose ether, 0.5-5 parts of starch ether, 3-4 parts of an additive and 57-84 parts of water. The raw materials used in the pervious concrete are common and easy to obtain, the production process is simple, and cellulose/cellulose ether and starch ether are added as thickening and water-retaining agents, so that the produced pervious concrete is suitable for long-distance transportation, high-strength pervious concrete can be prepared while good pervious rate is met, and the pervious concrete is suitable for production of common commercial concrete mixing plants.
本发明提供的一种透水混凝土及其制备方法，由以下重量份的组分组成：水泥200‑300份，矿粉30‑80份，粉煤灰30‑80份，碎石1400‑1700份，胶粉1‑5份，纤维素及纤维素醚0.5‑5份，淀粉醚0.5‑5份，外加剂3‑4份，水57‑84份，本发明所使用原材料常见易得，生产工艺简单，通过添加纤维素/纤维素醚、淀粉醚作为增稠保水剂，所生产的透水混凝土适用于远距离运输，在满足良好透水率的同时可制备出高强度透水混凝土，适用于普通商品混凝土搅拌站生产。
