Crack pouring material suitable for large temperature difference and salt freezing environment
The invention discloses a crack pouring material suitable for a large temperature difference and salt freezing environment. The crack pouring material is prepared by mixing the following raw materials in parts by mass: 25-30 parts of cement, 6-10 parts of a mineral admixture, 40-60 parts of sand, 3-8 parts of a functional component and 6-10 parts of water. The crack pouring material has the advantages of high strength, slight expansion, high workability, high trafficability, high freezing resistance and high sulfate corrosion resistance, and is suitable for repairing and reinforcing post-pouring cracks of concrete structures in large temperature difference and salt freezing environments. Compared with an unmodified crack pouring material, the anti-freezing performance is improved by 50%, and the sulfate corrosion resistance is improved by 50%.
本发明公开了一种适用于大温差、盐冻环境的灌缝材料。所述灌缝材料由以下原料按质量比混合而成：水泥25～30份、矿物掺合料6～10份、砂40～60份、功能性组分3～8份、水6～10份。上述灌缝材料具有高强度、微膨胀、高工作性、高通过性、高抗冻性、高抗硫酸盐侵蚀性，适用于大温差、盐冻环境下混凝土结构后灌缝修复、加固。相比于未改性灌缝材料，抗冻性能提升50％，抗硫酸盐侵蚀性能提升50％。
