The present study reports experimental works on Hybrid Fiber Reinforced Concrete (HyFRC) using a combination of steel and two types of polypropylene fibers available in India. In addition to routine testing of standard cube and cylinder specimens; displacement controlled flexural tests under monotonic loading arrangement are conducted on prism specimens using servo-hydraulic actuator to track the post crack behavior. Toughness and post-peak slopes are identified as parameters for the assessment of performance. It is also observed that a specimen with the lower post-peak slope and higher maximum defections exhibits higher flexural toughness. HyFRC is found to be superior to conventional concrete specimen and the best fiber proportion is assessed utilizing the parameters identified for performance evaluation. The microstructure of HyFRC matrix is studied to explore the possible reasons for improved performance of such specimens after initiation of cracking. © 2020; Associated Cement Companies Ltd..
