A Study on the engineering Properties of Repairing Epoxy-Mortar According to Hardener types for Structures under Underwater and Humidity

수중 및 습윤 환경구조물 보수용 에폭시 모르타르의 경화제 종류에 따른 공학적 특성에 관한 연구

Epoxy-mortar composites have been wildly used as finishing and repairing materials in the construction because of their excellent properties. Conventional epoxy-mortars and concretes have an inferior applicability and cost performance ratio due to the two component mixing of the epoxy resin and hardener. In this study, we examined the engineering effect of compressive strength and flexible strength according to the various epoxy-hardener in underwater and humidity environment, and evaluated the hardener types and physical effect of Epoxy mortar using cement binder in underwater and air condition. In this study, it was clarified that the engineering properties of repairing epoxy-motars were effected by the type of hardener.
