Concrete structure repairing and protecting material and application method
The invention discloses a concrete structure repairing and protecting material and an application method. The repairing and protecting material is of a two-component system, the first component system is a repairing component, and the second component system is a protecting component; the repairing component comprises the following raw materials in percentage by mass: 10-15% of a cement material; 8%-10% of fine sand; 25%-40% of coarse aggregate; 5%-8% of a fiber material; 8%-10% of inorganic filler; 25%-40% of water; the protective component comprises the following raw materials in percentage by mass: 18%-35% of diethanol amine; 20%-25% of lithium silicate; 5%-15% of sodium gluconate; and the balance of water. The mode that the repairing components are matched with the protection components is adopted, the repairing components and the protection components are constructed and mixed step by step to form the repairing enhancement layer, the surface compactness of the repaired structure is enhanced, the anti-permeability is improved, reinforcing steel bars in concrete are protected while repairing is conducted, and meanwhile the repairing and protecting effects of the reinforced concrete structure are achieved.
本发明公开了一种混凝土结构修复防护材料及应用方法；所述修复防护材料双组份体系，其中第一组份体系为修复组分，第二组份体系为防护组分；所述修复组分包括以下质量百分比的原料：水泥料10%‑15%；细砂料8%‑10%；粗骨料25%‑40%；纤维料5%‑8%；无机类填料8%‑10%；水25%‑40%；所述防护组分包括以下质量百分比的原料：二乙醇胺18％‑35％；硅酸锂20％‑25％；葡萄糖酸钠5％‑15％；余量为水。该发明采用修复组分配合防护组分的方式，且修复组分和防护组分分步骤施工，拌料形成修复增强层，在进行修复的同时，增强修复后结构表层致密性，提高抗渗性，保护混凝土中的钢筋，同时起到钢筋混凝土结构的修复和保护作用。
