The results were compared with cement as repair materials. The abrasion resistance of repair materials was determined at the ages of 3, 7, 28, 56 and 90 d. Table 7 enlists the measured values abrasion resistance in terms of wear depth. The depth of wear and repair materials age were found to be inversely proportional.
