The Use of Palm Kernel Shell and Ash
Abstract—This work reports the potential of using Palm Kernel (PK) ash and shell as a partial substitute for Portland Cement (PC) and coarse aggregate in the development of mortar and concrete. PK ash and shell are agro-waste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a
Abstract. The maximum coarse aggregate size used in concrete can impact on its strength. An investigation of the effect of coarse aggregate size and replacement level of granite with palm kernel shell (PKS) on the compressive and tensile strengths of PKS concrete were investigated.

Abstract Oil palm shell (OPS) is a waste from the agricultural sector and is available in large quantities in the tropical regions. This paper investigates the effect of the replacement of normal weight coarse aggregate by oil palm shells on the compressive strength, density, modulus of elasticity, workability and water absorption.

Rice Husk Ash in Concrete -Properties, Advantages
Variation of Properties of Concrete with Rice Husk. The incorporation of rice husk ash in concrete convert it into an eco-friendly supplementary cementitious material. The following properties of the concrete are altered with the addition of rice husk: The heat of hydration is reduced. This itself help in drying shrinkage and facilitate

A Review on Pineapple Leaves Fibre and Its Composites
Natural fibre based composites are under intensive study due to their ecofriendly nature and peculiar properties. The advantage of natural fibres is their continuous supply, easy and safe handling, and biodegradable nature. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography, and so forth. Pineapple leave fibre (PALF
Palm kernel meal is the main by-product of the palm kernel oil extraction process. It is a highly fibrous and medium grade protein feed, hence most suited to ruminant or rabbit feeding (Pickard, 2005). Palm kernel resulting from mechanical extraction contains 5-12% oil and solvent-extracted palm kernel meal contains 0.5-3% oil .
- Can oil palm shell be used as replacement course aggregate?
- The percentages of oil palm shell are used as replacement course aggregate by 0, 10, 20, 30 and 40% with water cement ratio 0.55 and 0.60. This study to investigate the effect on concrete by using oil palm shell as replacement course aggregates. The objectives of this study are to determine the wet properties, density and strength of the concrete.
- Can oil palm shell be used as lightweight aggregate in concrete?
- Review on oil palm shell (OPS) usage as lightweight aggregate in concrete. OPS treatment, inclusion of admixtures and fibres for better OPS concrete properties. Sustainable concrete production with OPS as alternative aggregate. Long-term study of OPS concrete properties is suggested for future studies.
- Are oil palm shells a good substitute for concrete?
- As a result, the OPS which are light and naturally sized were ideal for substituting aggregates in lightweight concrete construction. Studies by found that oil palm shells was the organic aggregate which is better impact resistance compared to normal weight aggregate.
- How does oil palm shell affect the workability of concrete?
- The workability of concrete will decrease due to increasing percentage of OPS. This happen because of increasing the specific surface as a result increases the quantity of palm kernel shell. When the oil palm shell is used by replacement of course aggregates the workability of concrete increases.
- Are palm kernel shells a good substitute for coarse aggregate?
- Comparison of mechanical and bond properties of oil palm kernel shell concrete with normal weight concrete. Int J Phys Sci;5(8):1231– 9. Ndoke P.N. (2006). Performance of palm kernel shells as a partial replacement for coarse aggregate in asphalt concrete. Leonardo El J Pract Technol ;5(9):145–52.
- Does palm oil mill OPs affect compressive strength and wet properties of concrete?
- In this study, the OPS were used as coarse aggregate replacement that supplied from palm oil mill to study the effects of the OPS on compressive strength and wet properties of concrete. Therefore, the aim of the study is to study the effect of OPS as coarse aggregate replacement on densities and compressive strength of concrete.
