Sewage-erosion-resistant anti-crack concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses sewage-erosion-resistant anti-crack concrete and a preparation method thereof. The anti-crack concrete resistant to sewage erosion is prepared from the following raw materials in parts by weight: 15 to 20 parts of cement, 90 to 100 parts of aggregate, 5 to 12 parts of fly ash, 5 to 8 parts of hydrotalcite, 10 to 15 parts of sodium methyl silicate, 3 to 5 parts of polyhedral oligomeric silsesquioxane modified polyvinyl alcohol fibers, 1 to 3 parts of auxiliaries and 3 to 5 parts of water. According to the anti-crack concrete resistant to sewage erosion, through the mutual synergistic effect of the polyhedral oligomeric silsesquioxane modified polyvinyl alcohol fiber, the active sodium silicate, the hydrotalcite and the fly ash, the compactness of the concrete is improved, the immersion of an erosion medium is reduced, and the erosion resistance of the concrete is enhanced.
本申请涉及混凝土领域，具体公开了一种耐污水侵蚀的抗裂混凝土及其制备方法。一种耐污水侵蚀的抗裂混凝土，包括以下重量份的原料：水泥15‑20份，集料90‑100份，粉煤灰5‑12份，水滑石5‑8份，甲基硅酸钠10‑15份，笼型聚倍半硅氧烷改性聚乙烯醇纤维3‑5份，助剂1‑3份，水3‑5份。本申请的一种耐污水侵蚀的抗裂混凝土通过笼型聚倍半硅氧烷改性聚乙烯醇纤维、积极硅酸钠、水滑石和粉煤灰，相互协同作用，提高混凝土的密实度，减少侵蚀介质的浸入，增强混凝土的耐侵蚀能力。
