- Abstract
- This article investigates the wear resistance of four rock types using the rotary abrasion test. The tested rocks include argillaceous rocks (mudstone and shale) and igneous rocks (granite and andesite). The wear volume of the rock specimen was measured with various wear time, normal loads, specimen lengths, and water conditions. It was found that the wear volume of rock specimen linearly increased with wear time and normal load per unit length. The Wear Volume Index was proposed to represent the wear volume of the rocks, which was measured to be the greatest for mudstone, followed by shale, granite, and andesite for both wet and dry conditions. The presence of water significantly affects the Wear Volume Index of argillaceous rocks, which increased by 60 % for mudstone and 25 % for shale. On the other hand, the effect of water was found to be insignificant for igneous rocks such as granite and andesite.
