Abstract

While the importance of maintenance increases with the aging of concrete structures, premature re-deterioration after repair remains a persistent problem. This is primarily due to incomplete removal of deterioration causes, such as chlorides, during the repair process. This study aims to secure the long-term performance of concrete structures by reviewing international repair guidelines (EN 1504, ACI 546R-14) and recent research trends in deterioration range estimation. International guidelines emphasize accurate estimation of the deterioration range, including potential deterioration areas, through systematic condition assessment, and recommend the use of non-destructive testing (NDT) techniques such as potential mapping. Furthermore, this study analyzes rational repair range setting methods and optimal repair strategies through empirical field studies and probabilistic prediction model research. The results confirm that complete removal of deteriorated areas and thorough surface preparation are key factors for successful repair, and suggest that preventive repair strategies can be economical and effective from a long-term perspective. This study is expected to serve as fundamental data for improving the quality and securing the long-term performance of concrete repair works in Korea.

콘크리트 구조물의 노후화가 진행됨에 따라 유지관리의 중요성이 커지고 있으나, 보수 후 조기 재열화 문제가 지속적으로 발생하고 있다. 이는 주로 염화물 등 열화 원인이 완전히 제거되지 않은 채 보수가 이루어지기 때문이다. 본 연구는 콘크리트 구조물의 장기공용성 확보를 위해 국제 보수 지침(EN 1504, ACI 546R-14)과 열화범위 산정 관련 최신 연구 동향을 고찰하였다. 국제 지침들은 체계적인 상태 평가를 통해 잠재적 열화 영역까지 포함하는 정확한 열화범위 산정을 강조하고 있으며, 이를 위해 전위 매핑 등 비파괴 검사 기법의 활용을 권장한다. 또한, 현장 실증 연구와 확률론적 예측 모델 연구를 통해 합리적인 보수 범위 설정 방안과 최적의 보수 전략을 분석하였다. 연구 결과, 열화부의 완전한 제거와 철저한 바탕면 처리가 보수 성공의 핵심 요인임을 확인하였으며, 장기적인 관점에서 예방적 보수 전략이 경제적이고 효과적일 수 있음을 시사한다. 본 연구는 국내 콘크리트 보수 공사의 품질 향상과 장기공용성 확보를 위한 기초 자료로 활용될 수 있을 것이다.
