High-compactness cement-based capillary crystalline rigid inorganic waterproof material and preparation method and use method thereof
The invention belongs to the technical field of building waterproof materials, and relates to a high-compactness cement-based capillary crystalline rigid inorganic waterproof material for a concrete surface layer and a preparation method and a use method thereof. The waterproof material is prepared from the following components in parts by mass: 40 to 60 parts of cement, 10 parts of rho aluminum oxide, 18 to 20 parts of calcium carbonate, 10 to 15 parts of flocculent active silicon and 5 parts of water-soluble pseudo-boehmite. The preparation method comprises the following steps: coating rho aluminum oxide with calcium carbonate, adding the rho aluminum oxide and flocculent active silicon into cement, stirring to prepare powder, and respectively carrying out waterproof packaging on the powder and pseudo-boehmite. The powder is prepared into cement-based slurry with water in use, pseudo-boehmite is dissolved in water to prepare alumina sol, the surface of concrete is coated with the alumina sol, and then the slurry is uniformly smeared on the surface of the concrete, or the alumina sol is mixed into the cement-based slurry to be uniformly smeared on the surface of the concrete.
本发明属于建筑防水材料技术领域，是一种用于混凝土表层的高密实度水泥基渗透结晶刚性无机防水材料，及其制备方法和使用方法。该防水材料构成的组分构成和质量份数为：水泥40‑60份、ρ氧化铝10份、碳酸钙18‑20份、絮状活性硅10‑15份、水溶性拟薄水铝石5份。制备方法是将ρ氧化铝用碳酸钙包覆后，同絮状活性硅一起加入水泥中搅拌配制成粉料，与拟薄水铝石分别防水包装。使用时用水将粉料制成水泥基浆料，拟薄水铝石溶于水制成铝溶胶，用铝溶胶涂刷混凝土表面后将浆料均匀涂抹在混凝土表面，或者将铝溶胶混入水泥基将料中，均匀涂抹在混凝土表面。
