ABSTRACT
Malaysia being the second largest palm oil producer in the world and has total palm tree planted area coverage of 3.8 million hectares. Every year, the production of palm kernel shell (PKS) as a waste from palm oil industry is approximately 4 million tones. The PKS has the potential to be used as coarse aggregate in concrete. PKS is hard and light and hence it can be utilized to replace conventional coarse aggregate to produce lightweight concrete. These types of waste materials, when properly processed, have shown to be effective as construction material.
