Five concrete mix proportions of a fixed wa- ter-cement ratio of 0.45 were considered in the study, but the constituent ma- terials, age of concrete and exposure contact conditions were varied. The coarse aggregate type employed in the study was crushed granite. The com- pressive strength and abrasion resistance of concretes were tested between at ages 7 to 70 days and 100 - 500 revolutions of abrasion wheels respectively. The study revealed that the compressive strength and abrasion resistance had the optimal performance when the coarse aggregate content was 45% and the worst performance when the fine aggregate content was 28.7% of the total weight of concrete constituents. There was a remarkable loss of concrete par- ticles to wear between 200 revs and 300 revs of abrasion wheel contact. Con- crete grade in excess of 60 N/mm 2 is required to resist abrasion beyond 200 revolutions of abrasion wheel contact on concrete specimens. Concretes in- vestigated also showed weak resistance to deep abrasion at and above 300 rev- olutions of abrasion wheel contact.
