Modified waterproof concrete and preparation method thereof
The invention provides a modified waterproof concrete. The modified waterproof concrete comprises cement, fine aggregate, gravel, water and a waterproof agent, the waterproof agent is prepared from a high-molecular polymer and water, the high-molecular polymer is polyvinyl alcohol or a polyvinyl alcohol modifier, and the polymerization degree of the high-molecular polymer is 1500-2000. Compared with a waterproof agent in the prior art, the waterproof concrete has the advantages that polyvinyl alcohol with certain molecular weight/polymerization degree or a polyvinyl alcohol modifier is used as the waterproof agent, a good waterproof performance improvement effect can be obtained by adding a small amount of the waterproof agent in the concrete preparation process, and the ideal waterproof purpose is achieved without reducing the important performance of the waterproof agent, so the preparation process of the waterproof agent is simplified, and the concrete has good waterproof performance.
本发明提供了一种改性防水混凝土，包括水泥、细骨料、碎石、水、防水剂，防水剂由高分子聚合物和水配制而成，高分子聚合物为聚乙烯醇或聚乙烯醇改性物，高分子聚合物聚合度为1500～2000。与现有技术中的防水剂相比，本发明以一定分子量/聚合度的聚乙烯醇或聚乙烯醇改性物作为防水剂，在混凝土制备过程中添加少量即可获得较好的防水性能改善效果，在不降低其重要性能下达到了理想的防水目的，简化了防水剂的配制工艺，并使混凝土具有良好的防水性能。
