Abstract

This paper presents a study on compressive strength of concrete and the resistance to sulfate attack of mortar containing ground palm oil fuel ash(POFA)from different sources namely RAPOFA, KLPOFA and BIPOFA. POFA was ground until the particle size was reduced to 45 μm. It was used to partially replace Portland cement TypeI, by20% by weight of binder. The concretes were investigated and tested for compressive strength at ages of 7, 28 and 90 days. For the durability of mortar exposed to sulfate attack, 25x25x285mm mortar bars were prepared and cured according to ASTMC 1012 prior to immersionin 5% sodiumsulfate Na 2 SO 4 and magnesium sulfate MgSO 4 solutions for up to 15 weeks. The results show that the compressive strength of RAPOFA and KLPOFA concretes were improved. Also,the resistance to sulfate attack of mortars containing POFA from different sources was improved compared with OPC mortar.
