Article Description

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 the counterweight loads applied in the WWA experiment, sample surfaces with polished and matte surfaces and different abrasive powders on the test results. In this study, a total of 48 (7x10x3cm) samples were used for the WWA tests and 24 (7x7x3cm) samples were used for the BA tests. As a result of the experiments, it was determined that the matte surfaces of the marble samples reveal more accurate results in the abrasion tests. When both artificial corundum and corundum (white fused alumina) powder are used in WWA and BA experiments, similar abrasion values are obtained on the samples. In addition, it is determined in the WWA experiment that the anisotropy of the sample is important and the counterweight affects the groove shape.
