Abstract
This research aims to utilize palm oil fuel ash (POFA) as a pozzolanic material for replacing portland cement. POFA was ground by ball milling until the median particle sizes were 19.91 (G1P) and (G2P). portland cement Type I was replaced by all POFA of 10–40% by weight of the binder. The effects of POFA fineness on the setting times, compressive strength, and expansion of mortars exposed to a 5% solution were investigated. It was found that the use of POFA to replace portland cement Type I caused an increase in water demand for normal consistency and setting times, depending on the fineness and level replacement of POFA. With 10% replacement of portland cement Type I by G1P or G2P, the compressive strengths of the POFA mortars were 102–104% of that of portland cement Type I mortar at . For sulfate resistance, the expansions at for all mortar bars containing G1P or G2P were less than those of mortar bars made from portland cement Types I and V. The results suggest that ground POFA is a good pozzolanic material and can be used to increase both the compressive strength and the sulfate resistance of mortar.
