When a section of a wooden water flume had to be replaced, it was necessary to test the resistance to abrasion by water-borne sediments of the various materials being considered for constructing the new water flume. A test method was developed that combined some of the concepts of ASTM C 779 and ASTM C 944. The test results indicated that even though steel had the greatest resistance to abrasion, when wear rates for the intended field thicknesses of the various materials were taken into account, the high-strength concrete alternatives had much lower life-cycle costs than the steel.
