Underwater non-dispersible concrete and preparation method thereof
The invention discloses underwater non-dispersible concrete composed of the following components by mass: 13.26%-14.11% of P.S32.5 cement, 3.04%-3.32% of fly ash, 23.87%-25.35% of lake sand, 49.70%-51.47% of natural rock, 0.67%-0.94% of plastic powder, 0.36%-0.38% of a flocculating agent, 0.61%-0.70% of an air entraining agent, 0.48%-0.53% of an anti-freezing agent and the balance being water, andthe sum of the mass percentages of all the components is 100%. The prepared concrete has good fluidity, cohesiveness and filling property, and underwater concrete does not need enclosure and the likefor waterproofing.
本发明公开了一种水下不分散混凝土，按照质量分数由以下组分组成：P·S32.5水泥：13.26％‑14.11％，粉煤灰：3.04％‑3.32％，湖砂：23.87％‑25.35％，天然岩石：49.70％‑51.47％，塑料粉：0.67％‑0.94％，絮凝剂：0.36％‑0.38％，引气剂：0.61％‑0.70％，防冻剂：0.48％‑0.53％，余量为水，以上各组分的质量百分比之和为100％。本发明制备的混凝土具有良好的流动性、黏聚性和填充性，水下混凝土不需要围护等进行防水。
