The Study on the Mechanical Properties of Recycled Concrete according to the Hybrid Fiber Volume Fraction
초록
영어
The purpose of this study was to investigate the optimal fiber volume fraction in concrete mixed with recycle aggregates. In this study, a total of 9 variables (① 0% steel fiber content with PVA fiber contents of 0%, 0.25%, 0.5% ② 0.75% steel fiber content with PVA fiber contents of 0% 0.25%, 0.5% ③ 1.5% steel fiber content with PVA fiber contents of 0% 0.25%, 0.5%) are set. However, 30% replacement ratio of recycled aggregates and 35% water-cement ratio are fixed. The results of the compressive strength (0.75% steel fiber, 0.25% PVA fiber content), the splitting tensile strength (1.5% steel fiber, 0% PVA fiber content) and the flexural strength (1.5% steel fiber, 0.5% PVA fiber content) show the excellent material performance.
