“…This continual increase in strength even after 1 year indicates that the biomass mortar does not deteriorate once the OPKS aggregates are encapsulated into the mortar matrix. Similar trends were reported for OPKS as coarse aggregates in the literature [13]. Fig.…”

Abstract.The utilization of waste materials which are abundant and cheap, especially from clean resources, has become more pressing than ever. This study investigates the influence of Oil Palm Biomass waste including the Palm Oil Fuel Ash (POFA), Oil Palm Kernel Shell (OPKS) and Oil Palm Fibre (OPF) on the compressive strength and chloride penetration of mortar. The POFA was used as cement replacement up to 80% in nano size. The mass ratio of fine aggregates to binder was 3:1. Test specimens 70×70×70 mm cube were prepared and cured in water for 28 days. Ordinary Portland cement (OPC) mortar was also prepared as control specimen. The specimens were immersed in Sodium Chloride solution up to 18 months. The evaluation was done by visual observation, ultrasonic pulse velocity and mass change before and after exposure. The mortar was then split into two and sprayed with 0.1N Silver Nitrate solution to see the depth of penetration. The test results revealed that biomass mortar showed high resistance to chloride penetration as compared to OPC mortar due to the reduction of cement content in the mixture. Besides, the reactive silica from nano POFA produced more crystalline formation thus, reduced the porosity and crack within the biomass mortar.

“…The durability of OPS concrete has also been studied previously. When cured in water, it was found that OPS concrete have water absorption and water permeability of about 11% and 6.4 x 10 -10 cm/s respectively at an age of 28 day (Teo et al 2006), which is comparable to other lightweight concretes such as those made from pumice aggregates (Güdüz and Uğur 2005;Hossain 2004). …”

This paper presents an investigation on the flexural behaviour of reinforced concrete beams produced from oil palm shell (OPS) aggregates. Utilising OPS in concrete production not only solves the problem of disposing this solid waste but also helps conserve natural resources. A total of 6 under-reinforced beams with varying reinforcement ratios (0.52% to 3.90%) were fabricated and tested. Data presented include the deflection characteristics, cracking behaviour, ductility indices and end-rotations. The investigation revealed that the flexural behaviour of reinforced OPS concrete beams was comparable to that of other lightweight concretes and the experimental results compare reasonably well with the current Codes of Practice. It was observed that beams with low reinforcement ratios satisfied all the serviceability requirements as per BS 8110.

“…Therefore, such features and properties make OPS aggregates resistance to wear and due to its low impact and crushing values, it makes them absorbance to shock [17]. [14,15,[17][18][19][20].…”

Toward Sustainability in Concrete Industry by Using Of Solid Wastes from Palm Oil Industry

Abstract. Nowadays, one of the most important construction materials is concrete. By the advances of the industries in the urban areas, concrete is considered as one of the highest demands. As a result, the large amount of unprocessed materials is needed for making concrete. In the meantime, the agricultural wastes and solid material disposal are giving serious damages to the environment. As a result, by employing the agricultural wastes as a cementitious material, the undesirable impacts of the concrete industry to the environment will be dramatically decreased. That's because the source of these newly developed concretes is both reliable and environmental friendly. In this study, the utilization of agricultural wastes as a complementary cementitious material for producing the concrete is explained. In addition, it discusses the possibility of deploying the agricultural wastes by considering their engineering, physical and chemical properties. In addition, the successful use of agricultural wastes from oil palm industry such as oil palm shell, palm oil fuel ash and palm oil fibre in the concrete mixture was reported.
