MECHANICAL PROPERTIES OF GLASS FIBER REINFORCED POLYMER WASTE

Abstract

This research investigates the mechanical properties of concrete incorporating glass fiber-reinforced polymer waste (GFRPW). The study examines the effects of different GFRPW fiber contents (0%, 0.5%, 1.0%, 1.5%, and 2.0% by cement weight) on workability, compressive strength, splitting tensile strength, and flexural strength of concrete. The results indicate that the workability of GFRPW-reinforced concrete decreases with increasing fiber content. However, the compressive strength improves as the GFRPW fiber content increases, with a maximum increase of 37.99% compared to the reference concrete. Additionally, the splitting tensile strength exhibits a maximum enhancement of 13.69%. These findings suggest that incorporating glass fiber-reinforced polymer waste enhances the mechanical properties of concrete, offering an environmentally friendly approach for repurposing waste materials in the construction industry.
