Anti-seepage and anti-crack cement-based mortar and preparation method thereof
The invention relates to the technical field of building mortar, and particularly discloses anti-seepage and anti-crack cement-based mortar, which is prepared from the following raw materials in parts by mass: 55 to 80 parts of cement, 35 to 50 parts of fly ash, 10 to 20 parts of desulfurized gypsum, 10 to 20 parts of glass beads, 14 to 20 parts of expanded perlite, 2 to 5 parts of acrylate emulsion, 2 to 6 parts of mortar reinforcing agent, 1 to 3 parts of polypropylene fiber, 1.5 to 3.2 parts of acrylic acid, 0.4 to 1 part of air entraining agent, 0.1 to 1 part of calcium formate, 1 to 2 parts of water reducing agent and 120 to 180 parts of water. The cement-based mortar is reasonable in design and convenient to operate, has the characteristics of high early strength and stable later strength development, is high in thermal insulation strength and excellent in anti-seepage and anti-cracking performance, improves the flexibility of the mortar, remarkably improves the fluidity of the mortar, is convenient to construct, and is suitable for large-scale popularization and application.
本发明涉及建筑砂浆技术领域，具体公开了一种防渗抗裂水泥基砂浆，原料按质量包括：水泥55‑80，粉煤灰35‑50，脱硫石膏10‑20，玻化微珠10‑20，膨胀珍珠岩14‑20，丙烯酸酯乳液2‑5，砂浆增强剂2‑6，聚丙烯纤维1‑3，丙烯酸1.5‑3.2，引气剂0.4‑1，甲酸钙0.1‑1，减水剂1‑2，水120‑180；本发明水泥基砂浆设计合理，操作方便，具有早期强度高，后期强度发展稳定的特点，保温强度高的同时防渗抗裂性能优异，并改善砂浆的柔韧性，显著提高砂浆流动性，施工方便，适于大规模推广应用。
