The Performance and Application of Repair System for the Exterior Wall According to the Durability Improvement in the RC Structure (Part1. Theoretical approach to the repair technic)

내구성 향상을 고려한 R.C조 외벽 보수 시스템의 성능과 그 활용 (제1보 : 열화 요인별 외벽 보수기술)

The reinforced concrcte structure were once belicved to have permanent durability. However, it is now spoiled by durability failure caused by the corrosion of embeded steel reingorcement carbonation. alkali-aggregate reaction and salt attack Recently. salt damage has been also spreading. Salt damage is found in concrete structures built using seasands or certain admixtures containing calcium chlorides and in coastal structures frequently caught in seawater spray or blown by seawind It is the aim of this study to investigate the performance and application of new repair system for the exterior wall according to the durability improvement in the RC structures.
