Abstract Abrasiveness as an intrinsic property of rocks defines the extent wear or loss when interacting with other materials. In engineering sectors like hard rock mining and tunnelling, comprehending abrasiveness holds paramount importance due to its direct effect on tool during excavation. Among diverse methods for assessing abrasiveness, Cerchar abrasivity test emerges most widely used approach. Over time, has garnered substantial attention from scholars, who have delved into factors influencing results testing conditions examined connection between physical-mechanical parameters their abrasiveness. Recent advancements in instrument expanded our ability measure additional cutting drilling, yielding fresh insights assessment, prediction, performance evaluation excavatability estimation. The test, coupled recent developments parameter measurement, promising potential enhancing comprehension practical implications. This review systematically traces evolution test. It commences overview origin progression, emphasizing pivotal role Furthermore, it consolidates categorizes research contributions various scholars regarding includes enhancements refinements apparatus, well investigations orientations effects different types rocks. Moreover, this illuminates broader applications interdisciplinary possibilities not only material science but also tribology. underscores how gleaned can be extrapolated areas beyond scope engineering.
