CROSS SECTION REPAIRING STRUCTURE OF REINFORCED CONCRETE STRUCTURE AND CROSS SECTION REPAIRING METHOD OF REINFORCED CONCRETE STRUCTURE
To provide a cross section repairing structure of a reinforced concrete structure in which an adhesive force of an interface between a cross section repairing material mixed with lithium nitrite having a high antirust effect and a cross section repairing material which is not mixed with lithium nitrite has been further improved, and to provide a cross section repairing method of the reinforced concrete structure.SOLUTION: A cross section repairing structure of a reinforced concrete structure includes: a concrete removal part which is formed by removing surface layer concrete in a defective part of an existing reinforced concrete structure until at least a part of a reinforced bar is exposed; and a repairing material which contains a cross section repairing material A containing lithium nitrite as an antirust agent for covering the periphery of the exposed reinforced bar and a lithium nitrite non-inclusive cross section repairing material B which is laminated on the cross section repairing material A via a primer layer. The repairing material is filled in the concrete removal part.SELECTED DRAWING: Figure 1
【課題】防錆効果の高い亜硝酸リチウムを混合した断面修復材と、亜硝酸リチウム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防錆剤として亜硝酸リチウムを含む断面修復材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亜硝酸リチウム非含有断面修復材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
