In the last four decades, numerous investigations have been undertaken on abrasion-erosion of concrete using various test methods. These have suggested the existence of different abrasion mechanisms, limitations of existing test methods, and inconsistencies on the importance of compressive strength to abrasion resistance of concrete. The objective of this review is to understand the mechanisms of concrete abrasion-erosion, assess the suitability of existing test methods to simulate field conditions, and investigate the relationship between abrasion resistance and compressive strength. It is found that concrete abrasion mechanisms are dependent on both transport modes of abrasive charge and the ratio of coarse aggregate to matrix hardness. The ASTM C1138 (underwater) test method appears to simulate all the critical modes of sediment-induced abrasion expected in field conditions and specific energy can be used as a framework to correlate ASTM C1138 test results with field measurements. With the exception of concrete with rubber aggregates, abrasion loss is found to fit a simple power function of its compressive strength, and no significant improvements in abrasion resistance can be gained by using concretes with compressive strengths exceeding 60 MPa (8.70 ksi). Also, the influence of cementitious additives and coarse aggregate properties is only significant at compressive strengths below the optimal value of 60 MPa (8.70 ksi).
