Post-Construction Quality Verification of In-Place Reinforced Concrete

構造物表層のコンクリート品質と耐久性能検証システム

Subcommittee on Post-Construction Quality Verification of In-Place Reinforced Concrete (JSCE 335) under Concrete Committee of Japan Society of Civil Engineers (JSCE) published the state-of-the-art report on the non-destructive inspection technique for measuring the quality of cover concrete of completed structures and the system for verifying durability of the structures based on the measured quality. Firstly, the significance of the implementation of the inspection was clarified by the review of the process of design, construction and maintenance. Then, a guideline for verifying the quality of cover concrete by the non-destructive inspection method such as air permeability test or water absorption test on site was proposed. In addition, the other guideline for improving the quality of cover concrete during the construction was proposed. Finally, the future of the durability design, prediction and maintenance utilizing the post-construction quality verification was discussed.土木学会「構造物表層のコンクリート品質と耐久性能検証システム研究小委員会（335委員会）」では，施工後に構造物表層のコンクリートの品質を確認する技術と，その品質を踏まえて構造物の耐久性能を検証するシステムの調査・研究・整備を目的とし，断続的に7年にわたる活動を行った。まず，国内外の設計・施工・維持管理システムの調査分析を行い，表層品質検査の導入意義を明確化した。その上で，検査に用いる非破壊試験方法の特長と課題を分析し，判定基準の考え方を示した。また，表層品質の確保・向上を図るための施工上の要点を現場施工心得として提示した。加えて，表層品質評価とリンクした耐久設計・将来予測・維持管理について論じた。
