High-strength pervious concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-strength pervious concrete and a preparation method thereof. The pervious concrete is prepared from the following components in parts by weight: 230 to 240 parts of cement, 148 to 152 parts of mineral powder, 45 to 55 parts of fly ash, 210 to 220 parts of sand, 1500 to 1540 parts of stones, 7.0 to 7.6 parts of a water reducing agent, 116 to 124 parts of water, 20 to 25 parts of a latex polymer, 0.69 to 0.72 part of sodium gluconate, 9.2 to 9.6 parts of a lotus leaf water repellent agent and 0.46 to 0.52 part of cellulose nanocrystals. The preparation method comprises the following steps: mixing and stirring the cellulose nanocrystal and 40-50% of water, then carrying out ultrasonic dispersion, and then mixing and stirring with the rest raw materials. The pervious concrete disclosed by the invention has relatively high mechanical properties and durability while the pervious rate and the pervious effect are ensured, and the application range is relatively wide.
本申请涉及混凝土领域，具体公开了一种高强度透水混凝土及其制备方法。透水混凝土包括以下重量份的组分：水泥230‑240份、矿粉148‑152份、粉煤灰45‑55份、砂子210‑220份、石子1500‑1540份、减水剂7.0‑7.6份、水116‑124份、胶乳聚合物20‑25份、葡萄糖酸钠0.69‑0.72份、荷叶疏水剂9.2‑9.6份和纤维素纳米晶体0.46‑0.52份；其制备方法为：先将纤维素纳米晶体和水总量的40‑50%混合搅拌，然后超声分散，之后再与其余所有原料混合搅拌。本申请的透水混凝土在保证透水率和透水效果的同时，兼具了较高的力学性能和耐久性，可应用范围较广。
