Some Comments and Suggestions for Wide Wheel Abrasion Test Used to Determine the Abrasion Resistance of Marbles
ABSTRACT: The most widely used standard test methods for determining wear of the marbles are Wide Wheel (Vertical)Abrasion (WWA) and Böhme Abrasion (BA) tests. In this study, it was aimed to determine the effect of thecounterweight loads applied in the WWA experiment, sample surfaces with polished and matte surfaces and differentabrasive powders on the test results. In this study, a total of 48 (7x10x3cm) samples were used for the WWA testsand 24 (7x7x3cm) samples were used for the BA tests. As a result of the experiments, it was determined that the mattesurfaces of the marble samples reveal more accurate results in the abrasion tests. When both artificial corundum andcorundum (white fused alumina) powder are used in WWA and BA experiments, similar abrasion values are obtainedon the samples. In addition, it is determined in the WWA experiment that the anisotropy of the sample is importantand the counterweight affects the groove shape.
