| Abstract | The aim of this research was to study the abrasion of pozzolan concrete. Fly ash, palm oil fuel ash and bagasse ash were ground until their particle was retained on sieve No.325 less than 5%. All pozzolans were used to replace Portland cement type I in range of 0-60% by weight of cementitious material. Concrete samples were cast with the water to cementitious ratio (w/c) at 0.40, 0.45 and 0.50. All samples were cured in moist condition until the testing age. The strength and abrasion were tested in accordance with the ASTM C1138 (under water method) at age 28 days. Pozzolan concrete were also observed by placing as a pavement in traffic road. It was found that the trend of the abrasion resistance of concrete was inversely to the compressive strength. In addition, the abrasion resistance was affected by the cement replacement and type of pozzolanic materials.
