Preparation method of pervious concrete admixture
The invention discloses a preparation method of a pervious concrete admixture and pervious concrete made of the admixture. The pervious concrete admixture is prepared from the following components in parts by weight: 15 to 35 parts of redispersible latex powder, 15 to 25 parts of a water reducing agent, 5 to 10 parts of a water-retaining agent, 8 to 15 parts of epoxy resin and 10 to 20 parts of a carbon nanotube-glass fiber-piperidine ionic liquid composite material. By adopting the pervious concrete admixture, not only can the binding power of cement paste and aggregate be effectively enhanced, but also the working performance of pervious concrete can be effectively improved, the strength and the pervious coefficient of the pervious concrete are improved, and the service life of the pervious concrete is prolonged.
本发明公开一种透水混凝土外加剂的制备方法及使用该外加剂制成的透水混凝土，此种透水混凝土外加剂由重量份数为：可再分散乳胶粉15～35份、减水剂15～25份、保水剂5～10份、环氧树脂8～15份、碳纳米管‑玻璃纤维‑哌啶离子液体复合材料10～20份，采用此种透水混凝土外加剂不但能够有效增强水泥浆体与骨料的粘结力，还能够有效改善透水混凝土的工作性能、提高透水混凝土的强度和透水系数，延长透水混凝土的使用寿命。
