Carbon fiber-reinforced concrete (CFRC), a composite material, has gained significant attention in recent years due to its enhanced mechanical properties and durability. This research explored the incorporation of waste glass (WG) as a partial replacement for coarse aggregate in CFRC, and to investigate its effects on the strength properties of the composite material. The literature review presents an overview of the properties of carbon fiber, waste glass, followed by an analysis of previous studies on CFRC incorporating waste glass. The findings suggest that waste glass can improve the mechanical properties of CFRC, such as compressive strength, flexural strength, and impact resistance. The methodology includes density of CFRC, slump, durability compressive strength and split tensile strength tests. The slump test results showed that the workability was a true slump for all replacement percentage of waste glass and this result showed the presence of sufficient cohesion in the mix to prevent shear or collapse slump at the levels of replacement considered. The 7-, 14-, 28- and 60-days curing regime showed an overall decline in compressive strength with increase in percentage WG as the 0%, 5%, 10% outshining the latter 15% and 20% partially replaced specimens. The 90 days specimens showed persistent growth in compressive strength with increasing in percentage WG replacement in accordance with the well-established pattern of compressive strength growth. The 0%, 15% and 20% waste glass replacement showed progressive increase in splitting tensile strength with aging curing regime. The durability water absorption test showed that, by partially replacing coarse aggregate with crushed waste glass, the rate at which the concrete absorbs water decreases with increasing percentage of waste glass. The use of waste glass contributes to sustainable construction practices by reducing the environmental impact associated with glass waste disposal.
