Abstract: Cylindrical members are used in Civil application. Hence in the design, the performance of those members is needed. The present investigation presents comparison of M40 grade concrete cylinders wrapped with and without Glass Fiber Reinforced Plastic (GFRP) sheet. For this purpose, standard cylindrical specimens 150 mm x 300 mm were prepared and tested with and without wrapping of GFRP sheet) to find compressive strength and elastic constants. The concrete cylinders with and without wrapping of GFRP sheet are tested under compression till failure. The load, lateral and longitudinal strains are measured. The secant modulus is increased by 40.25%, Poisson’s ratio is decreased by 5.88% and large decrease in lateral & longitudinal strains observed for concrete cylinder wrapped with GFRP sheet compared to without GFRP sheet. The compressive strength is nearly same.
Keywords: Compressive Strength, Elastic Constants, GFRP M40 Grade.
