Behaviour of structural properties of fiber reinforced high strength concrete beams subjected to static loads

摘要

This investigation has been conducted to assess the static structural properties of high strength concrete (HSC) beams utilizing chopped basalt stands fiber (CBSF), hybrid fiber (HYF) of (CBSF + polyvinle fiber (PVAF)) and PVAF as internal strengthening materials. The effect of the three type fibers on the structural properties of HSC beams subjected to static loads has been done using three point's flexural load. The test results showed that the yield and ultimate static flexural loads of fiber reinforced HSC beams were found to increase as compared to that of the control mixes. In addition, the middle-span deflection of HSC beams was found to increase as compared to that of plain HSC.
