Repair and Retrofit System of Concrete Structures using Fiber Glass and Epoxy Composite Sheets, Improved Through Utilization of Silica fume and Mechanical Saturator

실리카흄과 현장기계함침을 이용한 유리섬유 복합재(CAF)의 콘크리트 구조물 보수보강공법

Repair and retrofit system of concrete structures has been developed from conventional reinforced concrete overlaying, steel plate bonding and recently to fiber composite systems. Research and study on carbon, aramid, and glass fiber composite system has been actively carried out from all over the world Glass fiber composite is proved to be competitive technically and enconomically, among fiber composite system. CAF system is a system developed locally using all domestic materal, glass fabric and epoxy, and improved in shear bonding property by utilizing silica fume mixed with epoxy. All the tests on material properties, structural behavior, constructiveness at site and quality control procedure proved to be most appropriate system so far developed. Futher research work is and will be under progress for utilization of this system which will be applied to more adverse situation.
