The utilization of fly ash in concrete has long been in practice, and it is expected that their utilization in concrete construction will continue to increase in the years to come. In general practice the amount of fly ash employed in structural concrete is relatively small but the advantages are manifold. In recent years, however, large amount of fly ashes are being utilized both at research level and in field applications to achieve the desired benefit out of the pozzolanic character. One of such pozzolanic materials is palm oil fuel ash (POFA), a waste material obtained on burning of palm oil husk and palm kernel shell in palm oil mill boilers. This study presents some experimental results on the performance behavior of high volume POFA in concrete. Concrete specimens containing 50% POFA were made and short- term strength and shrinkage behavior were studied and compared with that of concrete containing 100% OPC, as control. It has been found that the development of strength in POFA concrete at all ages of 1, 7 and 28 days were lower than that in OPC concrete. With superplasticizer, however, a significant development in strength was noticed. Among the curing methods, the water curing has been found to produce the best result. The short-term investigation on shrinkage reveals that the shrinkage strain of high volume POFA concrete was higher than that of concrete containing OPC alone.
