Acid-etching-resistant concrete structure repairing material, preparation method and repairing construction method
The invention relates to an anti-acid-etching concrete structure repairing material which comprises a material A and a material B, the material A is prepared from the following components in parts by mass: 10 to 30 parts of a sodium silicate solution, 10 to 30 parts of a potassium silicate solution, 10 to 20 parts of silica sol, 0.05 to 0.5 part of a surfactant, 0.1 to 1 part of a reaction retarder, 0.1 to 0.5 part of a reducing agent, 0.2 to 2 parts of a reaction accelerant, 0.05 to 0.5 part of an anti-freezing agent, 0.1 to 1 part of a metal ion blocking agent, 0.1 to 0.5 part of an anti-rust agent, 0.1 to 0.5 part of fluosilicate and 40 to 70 parts of deionized water; and the material B comprises the following components in parts by weight: 10-35 parts of calcium hydroxide, 5-10 parts of an acid-resistant agent, 0.05-1.5 parts of a surfactant, 5-35 parts of sodium hydroxide and 30-85 parts of deionized water. Compared with the prior art, the acid-corrosion-resistant concrete structure repairing material not only can permeate into concrete, improve the compactness of a shallow layer of the concrete and enable the surface of the concrete to show the characteristics of low permeability and high compactness, but also has the characteristic of acid corrosion resistance, and can exert a lasting protection effect even if being used in an acid environment.
本发明涉及一种抗酸蚀混凝土构筑物修复材料，其包括A材料和B材料；按质量计，A材料包含：硅酸钠溶液10‑30份、硅酸钾溶液10‑30份、硅溶胶10‑20份、表面活性剂0.05‑0.5份、反应延迟剂0.1‑1份、还原剂0.1‑0.5份、反应促进剂0.2‑2份、抗冻结剂0.05‑0.5份、金属离子封锁剂0.1‑1份、防锈剂0.1‑0.5份、氟硅酸盐0.1‑0.5份、去离子水40‑70份；B材料包含：氢氧化钙10‑35份、耐酸剂5‑10份、表面活性剂0.05‑1.5份、氢氧化钠5‑35份、去离子水30‑85份。相比现有技术，本发明的抗酸蚀混凝土构筑物修复材料，不仅可以渗透到混凝土内部，提高混凝土浅层密实性，使混凝土表面表现出低渗透高密实的特点，还具有抗酸蚀特点，即使服役于酸性环境中，也能发挥持久的防护效果。
