Slabs are the most important member in structures that endure various forces and one of the forces that slabs commonly fail under is the impact loads, steel bars reinforced concrete is extensively used in structural members but construction work need more advanced material to resist impact forces. The aim of the present study is to examine the effects of using hybrid concrete in addition to Glass Fiber Reinforced Polymer GFRP rebar on impact resistance comparing to normal concrete NC with steel rebar. A free drop mass impact test setup will be employed to study the impact behaviour of hybrid concrete slabs reinforced with GFRP bars. In this investigational study, one hybrid concrete slab and one NC slab used as control specimen were tested for impact. One (1550×1550 mm) hybrid concrete slab containing 50% reactive powder concrete (RPC) and normal concrete (NC) reinforced with GFRP and one normal concrete reinforced with steel, both slabs have a reinforcements ratio of 0.00448 have been prepared and exposed to 7 m free drop mass. The outcomes from present research demonstrate that slab having RPC and reinforced with GFRP are improved in resisting and enduring impact loads also less scattered pieces comparing to the NC slab, furthermore slab containing RPC giving low deflection comparing to the NC slabs.
