Abstract

This paper investigates the compressive behavior of reinforced concrete columns reinforced with Poly Propylene fibers. The Experimental results obtained from 3 combinations of concrete column specimens with normal strength and fiber reinforcement content including 0.5%, 1% and 1.5% compared with the standard combination without fiber reinforcement content. Data show that the compressive strength of columns increases when fiber reinforcement is present in the concrete. The appearance of fiber reinforcement prevents side expansion deformation, thereby enhancing axial compression. Overall, the results obtained give a positive view on the possibility of recycling plastic waste as materials in the construction industry, especially as fibber for concrete materials.
