In this research, applicability of sandblast method for evaluation on abrasion resistance of inorganic material was examined. Influence on the difference of abrasive particle size to test result and decrement of abrasion performance with time increment were examined as estimation of fundamental performance of sandblast. Additionally, surface condition, mass decrement and abrasion depth of mortar specimen was evaluated. As a result, it was confirmed that mass decrement of specimen increased with increment of abrasive size. On the other hand, decrement of abrasion performance with time increment was not confirmed. It was clarified that variation of test result increased with increment of test time, and test result was stable at 10 and 30 seconds of test time. Moreover, the abrasion depth of sandblast method at 30 seconds of test time was equivalent with that of abrasion tester using water jet with sand method at 10 hours.
