Experimental investigation on GFRP reinforced concrete slabs subjected to impact load.

This paper presents the results of an experimental study conducted on Glass Fibre Reinforced Polymer (GFRP) reinforced concrete slabs subjected to impact load test. Conventional steel rebars are also considered for comparison purpose. GFRP rebars can be used as a reinforcing material to enhance the impact resistance of structural elements. GFRP is more durable compared to conventional steel reinforcement and possesses high strength to weight ratio. The current study aims to provide an overall idea of the impact resistance of slabs reinforced with GFRP rebars at different proportions. The comparison of results between GFRP and steel reinforced concrete slabs under impact loading is also performed. The number of blows taken for getting initial cracks and collapse is observed. The results prove that replacement of conventional steel reinforcement by GFRP rebars is beneficial. [ABSTRACT FROM AUTHOR]
