CROSS SECTION REPAIR STRUCTURE OF REINFORCED CONCRETE STRUCTURE AND CROSS SECTION REPAIR METHOD OF REINFORCED CONCRETE STRUCTURE
To provide a cross section repair structure for reinforced concrete structures and a cross section repair method for reinforced concrete structures, in which adhesion strength of an interface between a cross section repair material mixed with a chlorine immobilizing material with high anti-corrosion effect and the cross section repair material without the chlorine immobilizing material is further improved.SOLUTION: There is provided a cross section repair structure of a reinforced concrete structure, which comprises: a concrete removal section formed by removing the surface concrete in a defective section of an existing reinforced concrete structure until at least part of the reinforcing bars is exposed; and a repair material including a cross section repair material A containing a chlorine immobilizing material covering around the exposed reinforcing bars, and a cross section repair material B containing no chlorine immobilizing material, which is laminated to the cross section repair material A via a primer layer. The repair material is filled in the concrete removal section.SELECTED DRAWING: Figure 1
【課題】防錆効果の高い塩素固定化材を混合した断面修復材と、塩素固定化材を混合しない断面修復材の界面の付着力をさらに向上させた、鉄筋コンクリート構造物の断面修復構造、および鉄筋コンクリート構造物の断面修復方法を提供すること。【解決手段】既設鉄筋コンクリート構造物の欠陥部における表層コンクリートを鉄筋の少なくとも一部が露出するまで除去して形成されるコンクリート除去部と、露出した鉄筋の周囲を覆う塩素固定化材を含む断面修復材Ａ、及び該断面修復材Ａにプライマー層を介して積層される塩素固定化材非含有断面修復材Ｂを含む補修材とを有し、該補修材が前記コンクリート除去部に充填されてなる鉄筋コンクリート構造物の断面修復構造である。【選択図】図１
