Influence of Fiber Hybridization on Strength and Toughness of RC Beams

This paper focuses on the experimental investigation designed to study behavior of hybrid fiber-reinforced concrete (HFRC) beams under flexure and impact loading. The addition fibers can improve a number its properties. For optimal response, different types may be suitably combined produce HFRC. Optimized combinations fiber in composite with better engineering properties than that only one type. compared mechanical fresh hardened HFRC, Steel Fiber Reinforced Concrete (SFRC), conventional arrive at optimum content for improved by testing 135 specimens. Subsequently, steel was investigated without hybridization flexural loading, followed comparison results. achieved developing containing combination polypropylene fibers. Eighteen beam specimens size 1650×200×150 mm were tested investigation. Test outcomes demonstrated inclusion form could ensure superior performance terms resistance when incorporation single type reinforced concrete. Doi: 10.28991/CEJ-2022-08-03-010 Full Text: PDF
