Geopolymer coating material for rust prevention and corrosion prevention of steel bars and manufacturing and using method thereof
The invention relates to a geopolymer coating material for rust prevention and corrosion prevention of steel bars and a manufacturing and using method thereof. The coating material is composed of thefollowing materials: 90 parts of meta-kaolin, 10 parts of ordinary Portland cement, 10 parts of potassium hydroxide, 70 parts of potash water glass, 65-105 parts of water, 160-200 parts of natural fine sand, a high-performance polycarboxylate water reducer, which accounts for 1.2% of the total weight of meta-kaolin and ordinary Portland cement, and polypropylene fibers, which account for 0.25% ofthe total weight of meta-kaolin and ordinary Portland cement in unit volume. The beneficial effects of the invention are that: the material has mechanical properties for protecting the protective coating of steel bars, chloride ion permeability resistance, resistivity and bonding strength, is suitable for an anticorrosive protective layer of internal reinforcement of cast-in-place concrete or precast concrete members, can improve the durability of a concrete structure and effectively prolong the service life of the concrete structure, and does not influence the cooperative work of concrete andsteel bars.
本发明涉及一种用于钢筋防锈防腐的地聚物涂层材料及其制作使用方法，涂层材料由以下材料组成：偏高岭土90份，普通硅酸盐水泥10份，氢氧化钾10份，钾水玻璃70份，水65～105份，天然细砂160～200份，掺量为偏高岭土和普通硅酸盐水泥总重量的1.2％的高性能聚羧酸减水剂，掺量为单位体积偏高岭土和普通硅酸盐水泥总重量的0.25％的聚丙烯纤维。发明有益的效果是：该材料具有钢筋防护涂层所需的力学性能、抗氯离子渗透性、电阻率和粘结强度，适用于现浇混凝土或预制混凝土构件内部配筋的防腐保护层，能提高混凝土结构的耐久性，有效延长其使用寿命，同时不影响混凝土与钢筋的协同工作。
