Autogenous Property and Mock-up Test of the High Performance Concrete with Emulsified Refined Cooking Oil

유화처리 정제식용유(ERCO) 사용에 따른 고성능 콘크리트의 Mock-up 및 자기수축특성

In this study, mock-up test for high strength concrete with ERCO has been carried to analyse the effect of autogenous shrinkage reducing of using ERCO. The following results could be made as the conclusion. Results of EIS were lower than 2.5 and showed good resistance for separation of materials. For the setting time, specimen with ERCO showed delay of setting comparing with Plain. For the autogenous shrinkage, as the generation of saponification, capillary pores inside the concrete were filled by soap and the autogenous shrinkage has been obviously decreased. It could be identified that using ERCO in high strength showed good effect on reducing autogenous shrinkage in high strength concrete.
