친환경 고강도 강섬유 보강 콘크리트의 재료특성 평가

초록

This study was investigated the effected of blast furnace slag (BS) replacement ratio upon the compressive strength of concrete to find out optimized high strength concrete mixture. Then, using the optimized mixture added hooked steel fibers of various volume fractions and the resulting mechanical properties under compression and flexure were evaluated. Test results indicated that BS replacement ratios of from 50% and 60% and 0.76% volume fractions of hooked steel fibers were optimal in the strength. Lastly, will investigate other material properties for the optimal concrete which combination of blast furnace slag 60% and hooked steel fiber 0.76%.
