현장타설 고강도콘크리트의 시공성 및 강도특성에 관한 실험적 연구 ( THE EXPERIMENTAL STUDY OF WORKABILITY,PLACEMENT AND STRENGTH CHARACTERISTICS ON THE HIGH STRENGTH CONCRETE IN THE FILED )

The purpose of this reasearch is to establish the applicability of the High Strength Concrete in the field. We worked out the optimum mixing design about 500kg/cm2 High Strength Concrete for 28 days. Based on this, We cast High Strength Concrete in the actual model members including Columns, Bean and Wall. By the application, We could confirm the good workability and pumpability of the High Strength Concrete. Also we could obtain good results that compressive strength tests were 482kg/cm2(cylinder), 400kg/cm2 (core) for 7 days, 582kg/cm2 (cylinder),500 kg/cm2 (core) for 28 days and 629kg/cm2 (cylinder) for 56 days.
