초록

In this study, compressive strengths, elasticity modules and shrinkages of high strength concrete with 80~100MPa, which are usually applied in skyscrapers in Korea, were evaluated in regard to fiber and surface drying conditions. Also a comparison with ACI 209 Model Code, generally applied in structure designs in Korea, was carried out to secure a reliability of the study results. As a result, specimens mixed with fiber produced a reduction effect of shrinkage independent from the evaporation conditions of unsealed and sealed specimen. Shrinkage of unsealed specimen was decreased and compressive strength increased, but sealed specimens as autogenous shrinkage or self desiccation of specimen, shrinkage amount was increased as compressive strength was increased.
