Abstract

Oil palm empty fruit bunch (EFB) is a biomass waste abundantly produced by the oil palm industry in Malaysia. To minimize the environmental impacts, it needs to be properly disposed of or being rapidly consumed as a raw material of another industry. This study investigated the feasibility of substituting EFB in cement bricks, which is in high demand by the construction industry. A total of 120 specimens having the cement-to-sand (c/s) ratios of 1:2.5 and 1:3 were produced in the laboratory. EFB fibre was used to replace 10% to 25% of sand in the mix by volume. The specimens were tested for the compressive strength, density and water absorption after 28 days of casting. For the mix of 1:2.5 c/s ratio, 25% EFB content reduced 22% of density, decreased 59% of compressive strength and increased 43% of water absorption capacity of normal cement brick. This was mainly attributed to the porous cellular structure of EFB fibre that created a large volume of voids in the mix. Based on the feasibility evaluation, EFB fibre can only replace up to 15% and 10% of sand in the mixes of 1:2.5 and 1:3 c/s ratios respectively.

Abstract

Cement brick is an essential construction component, which uses cement as the primary binder. The cement industry was identified as the major contributor to carbon dioxide emission, which is a greenhouse gas. The application of agro-industrial waste as partial cement replacement can reduce the negative impacts on the environment. In this study, the palm oil wastes, namely Palm Oil Clinker Powder (POCP) and Palm Oil Boiler Ash (POBA), were used as partial cement replacement. A total of 60 specimens were prepared with 0%, 10%, 20%, and 30% cement replacement by POCP and POBA. The physical and mechanical properties of bricks, such as density, water absorption, voids, and compressive strength, were investigated. The results show that the brick with 20% CP and BA could be used as a severe weathering brick.
