Abstract: This paper presents the experimental investigations of concrete specimens reinforced with Glass fiber reinforced plastic (GFRP) reinforcements and quarry dust to improve the properties of concrete specimen. GFRP bars were used to reinforce the concrete columns instead of conventional rebars and that are experimentally investigated under axial compression to assess structural behavior of concrete. Four sets of column specimens of cross section 100 mm X 100 mm of length 600 mm were cast and tested under axial loading. Load-deformation characteristics of the specimens were plotted and energy absorption capacity, stiffness and ductility factor were calculated. The experimental results show that the column with GFRP reinforcement and quarry dust increases the strength properties of the column specimen. An analytical model has been developed using ANSYS 16 software in order predict the load deformation behavior of all specimens. The analytical results have been validated with the experimental results. It was found that the column with quarry dust and GFRP reinforcements shows better performance in all aspects. The investigation suggests that GFRP rebars as the best alternative to steel rebars in compression members.
