The invention discloses pervious concrete which comprises the following components: 50%-60% of aggregate, 10%-14% of cement, 5%-8% of water, 2%-3% of a mineral admixture, 4%-8% of resin and 3%-4% of an environment-friendly additive, and the environment-friendly additive comprises 0.7%-0.9% of a noise reduction agent, 1.7%-2.3% of a water reducing agent and 0.6%-0.8% of a defoaming agent. According to the pervious concrete disclosed by the invention, the mixed cement of the Portland cement and the fly ash cement is added, so that active silicic acid in the fly ash reacts with a calcium compound in a set cement matrix to generate relatively strong crystals, and the crystals have relatively good durability and freeze-thaw resistance; meanwhile, the fly ash cement is relatively small in dry shrinkage and relatively high in crack resistance, and the crack resistance of the concrete can be further improved when the fly ash cement is mixed with the Portland cement for use.
本发明公开了一种透水混凝土，一种透水混凝土，包括以下组分：骨料50％‑60％、水泥10％‑14％、水5％‑8％、矿物掺合料2％‑3％、树脂4％‑8％、环保型添加剂3％‑4％，其中环保型添加剂包括降噪剂0.7％‑0.9％、减水剂1.7％‑2.3％、消泡剂0.6％‑0.8％，以上百分比为质量百分比，本发明一种透水混凝土，通过添加硅酸盐水泥和粉煤灰水泥的混合水泥，使其粉煤灰中的活性硅酸与水泥石基体中的钙化合物反应生成较强的结晶，这种结晶具有较好的耐久性和抗冻融性，同时粉煤灰水泥的干缩性较小，抗裂性较高，与硅酸盐水泥混合使用，可以进一步改善混凝土的抗裂性能。
