Concrete anti-corrosion admixture as well as preparation method and use method thereof
The invention discloses a concrete anti-corrosion admixture as well as a preparation method and a use method thereof, and the anti-corrosion admixture comprises the following components in parts by weight: 40-50 parts of GHL powder, 45-55 parts of poly (p-phenylene benzobisoxazole) fiber, 20-30 parts of light calcined magnesia and 5-10 parts of nano cellulose. Wherein the GHL powder is prepared from polyacrylamide and modified tuff-limestone mineral powder. By improving the compactness and hydrophobicity of the concrete and reducing the decomposition of calcium hydroxide, the calcium dissolution of the concrete is delayed, and the corrosion resistance of the concrete is improved.
本发明公开了一种混凝土抗溶蚀外加剂及其制备方法和使用方法，所述抗溶蚀外加剂包括以下组份：按照重量份数计，40～50份GHL粉末，45～55份聚对苯撑苯并二噁唑纤维，20～30份轻烧氧化镁，5～10份纳米纤维素；其中GHL粉末包括聚丙烯酰胺、改性凝灰岩‑石灰岩矿粉。本发明通过提升混凝土密实性和疏水性，减少氢氧化钙的分解，从而延缓混凝土的钙溶出，提高混凝土的抗溶蚀性能。
