JMS_V5_N2_RP3 Abrasion Resistance of Some Rajasthan Marble Stones Subjected to Varying Loads and Sliding Speeds according to EN: 14157 Standards Bhargav Prajwal Pathri Rohit Chaudhary Harveer Singh Mali R. Nagar Journal on Material Science 2347–615X 5 2 27 34 Abrasion Resistance, Sliding Speed, Correlation, Contact Load, Thin Sectioning, Petrology Abrasion is an important phenomenon to know the mechanical erosion of rocks, which generally occurs due to the different elements that are in constant contact with the surface of the rock. Abrasion leads to decrease in mechanical and aesthetical properties. Typical abrasion testing was performed on three different marbles using varying loads and sliding speeds according to European standard EN 14157. From experiments, it was observed that the abrasion wear generally increased with respect to the applied load. However, it is also observed that Makrana and Andhi marbles showed a linear behaviour than Bhainslana marbles indicating that they are less sensitive to the increasing loads. The abrasion wear of marbles increased linearly with respect to sliding speed initially and then started decreasing with further increase of sliding speed. Further, correlation analysis was done to rank according to abrasive wear of the marbles with respect to load and speed. July – September 2017 Copyright © 2017 i-manager publications.
