采用水泥裹石法成型透水混凝土，研究了不同水泥用量、粉煤灰、矿粉不同取代水泥量、特细砂和机制中砂掺量对透水混凝土强度和透水系数的影响。结果表明，随着水泥用量的增大，透水混凝土的抗压强度和抗折强度均增大，而透水系数随着水泥用量的增加而下降。粉煤灰和矿粉取代水泥来配制透水混凝土，透水混凝土的7d和28d抗压强度均有所下降，且早期强度下降明显。透水混凝土中掺入特细砂和机制中砂都可以使透水混凝土内部更加密实，提高其抗压强度；当使用特细砂和机砂双掺时，增强效果大于单掺。

Using cement binding up stone manufacturing pervious concrete, the effects of different amount of cement, fly ash, slag with different cement replacement volume, superfine sand and manufactured medium sand content on the strength and permeability coefficient of pervious concrete are studied. Under the experimental conditions the results show that with the increase of amount of cement, the compressive strength and flexural strength of pervious concrete are increased, while the permeability coefficient increases with amount of cement decreased. Manufacturing pervious concrete with fly ash and slag to replace cement, the 7d and 28d compressive strength of pervious concrete are decreased, and the early strength decreased significantly. The superfine sand and manufactured medium sand mixing mechanism of pervious concrete can be made of pervious concrete internal denser, increase the compressive strength. When using superfine sand and manufactured sand mixed, the reinforcing effect is better than using the single doped.
