ISRM Suggested Method for Determining the Abrasivity of Rock by the CERCHAR Abrasivity Test

Rock abrasivity plays an important role in characterizing a rock material for excavation purposes. Abrasion can be dened as the wearing or tearing away of particles from the surface. The CERCHAR Abrasivity Test is intended as an index test for classifying the abrasivity of a rock material. The test...

Zusammenfassung:Rock abrasivity plays an important role in characterizing a rock material for excavation purposes. Abrasion can be dened as the wearing or tearing away of particles from the surface. The CERCHAR Abrasivity Test is intended as an index test for classifying the abrasivity of a rock material. The test measures the wear on the tip of a steel stylus having a Rockwell Hardness of HRC 55
