Investigation of abrasion of concrete containing pozzolan

Abstract

The aim of this research was to study the abrasion of pozzolan concrete. Fly ash, palm oil fuel ash andbagasse ash were ground until their particle was retained on sieve No.325 less than 5%. All pozzolanswere 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. Allsamples were cured in moist condition until the testing age. The strength and abrasion were tested inaccordance 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 resistanceof concrete was inversely to the compressive strength. In addition, the abrasion resistance wasaffected by the cement replacement and type of pozzolanic materials.
