In recent times, Glass Fiber Reinforced Polymer (GFRP) is widely employed in constructional members. Slabs sustain several forces and one of the forces that slabs usually fail to resist is the impact forces. GFRP bars are introduced as a substitute to traditional steel bars. The aim of the current research is to study the effects of using hybrid concrete as well as GFRP reinforcements on impact resistance compared to normal concrete NC with steel reinforcements. A free drop mass impact test setup will be used to examine the impact behaviour of hybrid concrete slabs reinforced with GFRP bars. Current study, one hybrid concrete slab and one NC slab used as control specimen were tested for impact. One (1550×1550 mm) hybrid concrete slab having 50% reactive powder concrete (RPC) and normal concrete (NC) reinforced with eight GFRP bars and one normal concrete reinforced with six steel bars, slabs have a reinforcements ratio (0.00448 and 0.006) for RPC and NC slabs correspondingly have been set and exposed to 7 m free drop weight. The results from current study show that slab with RPC reinforced with GFRP are better in resisting and enduring impact forces also fewer scattered fragments and offering low deflection comparing to the NC slab.
