Lightweight aggregate concrete (LWAC) material has been used for over 2000 years, and its use has been widespread for the past 90 years because it has a low density and will subsequently reduce the total deadweight on lower structural members, which reduces construction time and overall construction cost. Several attempts have been made to incorporate waste tire particles in the form of coarse, fine and a combination of both in concretes and mortars for the past two decades. An incorporation of waste tire particles in concrete and mortars had reported to produce low mechanical properties of the composite mixtures. Thus, chemicals and additives are introduced to improve the strengths, but the mixture become more expensive. In this research, oil palm fruit fibre used as a greener and more cost-effective approach to improve the tire crumb mortar composite strengths. The addition of palm fruit fibre to the matrix result in an increase in the water absorption value due to the high void content of the fibre causing more absorption of water during hydration.
