Abstract
This paper presents the use of palm oil fuel ash as a pozzolanic material in producing high-strength and high-workability concrete. Portland cement Type I (CT) was partially replaced with ground palm oil fuel ash (PA). PA with 2–5% by weight retained on a sieve No. 325 was used. The concrete mixtures were made with portland cement Type I containing 10, 20, and 30% of PA. Compressive strength, coefficient of water absorption, rapid chloride penetration and corrosion resistance of concretes were determined. Test results indicated that the high-strength high-workability concrete can be achieved by using PA to replace portland cement Type I up to 20%. The resistance to chloride-induced corrosion of concrete containing PA as measured by accelerated corrosion test with impressed voltage is significantly improved in comparison to that of CT concrete.
