High-strength impervious concrete and production method thereof
The invention relates to the technical field of impervious concrete, and particularly discloses high-strength impervious concrete and a production method thereof. The high-strength impervious concrete is mainly prepared from the following raw materials in parts by weight: 650 to 780 parts of aggregate, 500 to 600 parts of sand, 280 to 400 parts of cement, 80 to 120 parts of fly ash, 100 to 200 parts of water, 25 to 40 parts of a water reducing agent, 75 to 90 parts of an admixture and 80 to 150 parts of an anti-permeability agent, the anti-permeability agent is prepared from the sum of mass of polyoxyethylene and sorbitan fatty acid ester and nickel salt according to the mass ratio of (2.5-4): (4-7), and the admixture is at least two of coagulated limestone powder, limestone powder and quartz powder. The high-strength impervious concrete can be used for water conservancy and hydropower engineering, building construction and the like, and has the advantages of high strength and good impervious performance.
本申请涉及抗渗混凝土技术领域，具体公开了一种高强度抗渗混凝土及其生产方法。一种高强度抗渗混凝土，主要由如下重量份数的原料制成：骨料650‑780份、砂500‑600份、水泥280‑400份、粉煤灰80‑120份、水100‑200份、减水剂25‑40份、掺合料75‑90份、抗渗剂80‑150份；所述抗渗剂由聚氧化乙烯、失水山梨醇脂肪酸酯的质量之和与镍盐按质量比(2.5‑4):(4‑7)组成，掺合料为凝灰石粉、石灰石粉、石英粉中的至少两种。本申请的高强度抗渗混凝土可用于水利水电工程、建筑施工等，其具有强度高、抗渗性能好的优点。
