%X Wear resistance of high-volume fly ash concrete (HVFA) intended for pavement applications is presented in this paper. In India, yearly production of fly ash is more than 100 million tons. Majority of fly ash is of Class F type. Out of which 20-25% is being utilized in cement-based materials. In order to increase its percentage utilization, an investigation was carried out for its large scale utilization. Concrete mixtures were prepared by replacing cement with 40, 50, and 60% of fly ash. Experiments were conducted for fresh concrete properties, compressive strength and wear resistance. Test results indicated that wear resistance of concrete having cement replacement up to 40% was comparable to the normal concrete. Beyond 40% fly ash content, concretes exhibited slightly lower resistance to wear in relation non-fly ash concretes. There is very good correlation between wear resistance and compressive strength (R2 value between 0.8482 and 0.9787) depending upon age.
