Regenerated pervious concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses regenerated pervious concrete and a preparation method thereof. The regenerated pervious concrete is prepared from the following raw materials in parts by weight: 230 to 386 parts of cement, 516 to 1411 parts of regenerated coarse aggregate, 0 to 1146 parts of gravel, 4 to 10 parts of polycarboxylic acid water reducing agent, 8 to 30 parts of fly ash, 4 to 18 parts of mineral powder, 11 to 23 parts of silica fume, 50 to 70 parts of waste rubber particles, 4 to 15 parts of polypropylene fiber frame material and 40 to 70 parts of water. The preparation method comprises the following steps: uniformly mixing the cement, the waste rubber particles, the silica fume and the polypropylene fiber frame material to obtain a mixture A; uniformly mixing fly ash and mineral powder to obtain a mixture B; mixing the rest raw materials, pouring half of water, and uniformly mixing to obtain a mixture C; and uniformly mixing the three mixtures, pouring the rest of water, and uniformly mixing. The regenerated pervious concrete has the advantages of good water permeability and strength.
本申请涉及混凝土的技术领域，具体公开了一种再生透水混凝土及其制备方法。再生透水混凝土其包括如下重量份的原料：水泥230‑386份、再生粗骨料516‑1411份、碎石0‑1146份、聚羧酸减水剂4‑10份、粉煤灰8‑30份、矿粉4‑18份、硅灰11‑23份、废橡胶颗粒50‑70份、聚丙烯纤维框架材料4‑15份、水40‑70份；其制备方法为：将水泥、废橡胶颗粒、硅灰、聚丙烯纤维框架材料混匀，得到混合物A；将粉煤灰、矿粉混匀，得到混合物B；将剩余原料混合，倒入一半水，混匀，得到混合物C；将三种混合物混匀，倒入其余水，混匀制得。本申请的再生透水混凝土，具有良好的透水性和强度的优点。
