Influence of adding steel – glass – polypropylene fibers on the strength and flexural behaviour of hybrid fiber reinforced concrete

•• The effect of adding three different type of fibers on strength and load -deformation behaviour have been examined.•• Strength effectiveness was observed in steel -polyester fiber combination and negative results in Glass- polypropylene combination.•• Load deflection performance and strain capacity are improved 17% higher than non-fibrous control concrete beam.
