Construction method of corrosion-resistant reinforced concrete structure
The invention relates to the field of reinforced concrete reconstruction construction, and discloses a construction method of an anti-corrosion reinforced concrete structure, which comprises the following steps: mixing Portland cement, fine aggregate, coarse aggregate, calcium chloride, a water reducing agent and water into concrete, and preparing a reinforced concrete prefabricated part; the two ends of the reinforced concrete prefabricated part are smeared with a preservative, the surface of the reinforced concrete prefabricated part is covered with a waterproof layer, closed curing is conducted for 26-28 days at the temperature of 20-22 DEG C, then alternate curing is conducted, and the reinforced concrete component is manufactured and put into use; and after the reinforced concrete member is put into use for 180-270 days, the surface of the reinforced concrete member is coated with a nitrite type corrosion inhibitor, after the reinforced concrete member is placed for t1 time, supplementary brushing is conducted, the supplementary brushing amount is 1/3-1/2 of the brushing amount, and the corrosion-resisting reinforced concrete structure is obtained. The corrosion-resistant reinforced concrete structure prepared through the method is good in corrosion-resistant effect and high in protection durability, and corrosion of marine concrete in the marine environment can be effectively prevented.
本发明涉及钢筋混凝土改造施工领域，公开了一种耐蚀钢筋混凝土结构的施工方法，包括以下步骤：将硅酸盐水泥、细骨料、粗骨料、氯化钙、减水剂和水混合成混凝土，制备钢筋混凝土预制件；钢筋混凝土预制件的两端涂抹防腐剂，在其表面覆上防水层，并在20‑22℃下封闭养护26‑28天后进行交替养护，制得钢筋混凝土构件并投入使用；钢筋混凝土构件投入使用180‑270天后，在其表面涂刷亚硝酸盐型阻锈剂，放置t1时间之后，进行补刷，补刷量为涂刷量的1/3～1/2，即得到耐蚀钢筋混凝土结构。该方法制得的耐蚀钢筋混凝土结构耐蚀效果好，防护持久性高，可有效防止处于海洋环境的海洋混凝土的腐蚀。
