Fiber-reinforced polymers (FRP) were recently used as a replacing reinforcement in concrete structures in view of their excellent resistance to corrosion, light weight, and high specific strength. A state of art of using carbon fiber grids as an internal reinforcement with self-consolidate concrete in two-way slab systems is presented here. The experimental program included studying the flexural performance of the carbon fiber grid as in comparison with the conversional welded steel wire mesh. This work is expected to find its application in parking garages to enhance the durability performance and extend the service life of the concrete slab members. The load - deflection curves, ultimate loads, energy absorption, and failure mode of simply supported slabs with different aspect ratios are discussed. The test results for simply supported slabs with aspect ratio of (1:1) showed that the FRP grid tended to fall within the criteria of minimum load requirements per ASCE7 as the steel wire reinforcement did. In addition, the slabs observed a limit of deflection (L/360) at approximately 50% of their ultimate loads.
