고로슬래그 미분말을 이용한 PVA섬유 보강 철근콘크리트 보의 구조성능 평가

In this study, in total nine R/C beams, using PVA Fiber with ground granulated blast furnace slag and recycled fine aggregate were tested under monotonic loading. In the material development, micromechanics was adopted to properly select the optimized range of the composite based on steady-state cracking theory and experimental studies on the matrix and interracial properties. Experimental programs were carried out to improve and evaluate the structural performance of the test specimens: the load-displacement, the failure mode, the maximum strength were assessed.
