Abstract

Malaysia being the largest producer and exporter of palm oil in the world, accounting for 52% of the total world oils and fats export in year 2006. The problem wastage of palm oil industry was increasing. In addition, the government also faced problems when forced to allocate more landfill for the disposal of concrete, one of the construction waste. Nowadays, the wastage of the palm oil a potential to be utilized as construction material as additional material to cement. Following a through literature review, recycled aggregates are aggregates derived from the processing of materials previously used in a product or in construction industry and POFA is a byproduct in palm oil mill. The main objective of this study is to determine the water absorption and compressive strength of recycled aggregate concrete containing POFA. There are 12 series of concrete mix with POFA and recycled aggregate used as additional material to cement were indicated as POFA-0%, POFA-lo%, POFA- 20%, POFA-30% and RA-0%, RA-50% and RA-100%. The slump test was conducted to determine the performance of fresh concrete. The hardened concrete will be testing its compressive strength and water absorption of POFA- concretes due to 7 and28 days of water curing ages. The results revealed that POFA- recycled aggregate concrete has lower water absorption and higher compressive strength compare with recycled aggregate concrete without POFA. The optimum additional POFA was 30% for concrete made from 100%NA produced a higher compressive strength and lower water absorption.
