Abstract: The present investigation has been carried out to study the performance of quaternary blended Hybrid Fiber Reinforced Concrete by using locally available materials. Incorporation of multiple blending Supplementary Cementitious Materials (SCMs) in concrete are growing in the construction industry due to economical and environmental benefits, and enhanced concrete properties. However, the concrete made with SCMs is not promising when subjected to short-time impact and dynamic load. Unreinforced concrete has low tensile strength and low strain capacity at fracture. Under impact loading, plain concrete fails suddenly in a brittle manner. To overcome this weakness, fibers are added in concrete to improve the mechanical properties. Steel, carbon, and polypropylene fibers are generally used in concrete. However, when the fibers are added as a hybrid having two or more combinations, the hybrid composites exhibit more attractive engineering properties in comparison with the addition of a single type of fiber in the composites. Fiber hybridization in multiple blending Portland cement concrete is becoming important due to environmental and structural considerations. In this investigation, a quaternary mix is proposed as the control mix in which Ordinary Portland Cement is partially replaced with Fly Ash, Rice Husk Ash and Lime stone Powder by weight of cement. Steel, carbon, and polypropylene fibers have been added in mono and hybrid form in the quaternary blended concrete mix. The twenty six different proportions of fiber addition in the concrete mix including control concrete have been investigated. newline
