Repairing method using electrochemically compatible geopolymer concrete for repairing
The invention provides a repairing method using electrochemically compatible geopolymer concrete for repairing, and relates to the technical field of reinforced concrete. Comprising the following steps: mixing fly ash, slag powder and silicon powder, and carrying out dry mixing to obtain a first mixture; a mixed solution is added into the first mixture, the mixed solution comprises potassium silicate water glass, water and an additive, stirring is conducted after the mixed solution is added, and a second mixture is obtained; aggregate and PVA fibers are added into the second mixture to be stirred, and the electrochemically compatible polymer concrete for repairing is obtained; connecting the exposed old steel bars of the to-be-repaired part with the new steel bars for repairing by using stirrups to form an embedded steel bar structure; and the to-be-repaired part is poured with electrochemically compatible geopolymer concrete for repairing, the embedded steel bar structure is covered, and repairing is completed through maintenance. The geopolymer concrete is used for repairing the corroded structure, the macroscopic corrosion effect of steel bars in the new and old concrete can be reduced, and the electrochemical incompatibility and corrosion resistance of the new and old concrete are improved.
本发明提供了一种使用电化学兼容的修复用地聚物混凝土的修复方法，涉及钢筋混凝土技术领域。包括步骤：将粉煤灰、矿渣粉和硅粉混合后干拌，获得第一混合物；向第一混合物中添加混合液，混合液中包括硅酸钾水玻璃、水和外加剂，添加混合液后搅拌，获得第二混合物；向第二混合物中添加骨料和PVA纤维搅拌，获得电化学兼容的修复用地聚物混凝土；使用箍筋连接待修复部位暴露的旧钢筋和修复用新钢筋，形成预埋钢筋结构；使用电化学兼容的修复用地聚物混凝土浇筑待修复部位，覆盖预埋钢筋结构，并养护完成修复。本发明利用地聚物混凝土修复腐蚀后结构，可以降低新旧混凝土中钢筋的宏观腐蚀效应，改善新旧混凝土的电化学不相容性和抗锈蚀性。
