Abstract
Ten sedimentary rock samples including sandstones, limestones and an iron ore were collected from various locations of District Khushab, Mianwali and Trans Indus area (Punjab, Pakistan). The samples were subjected to Cerchar and LCPC Abrasivity tests for determination of their abrasivity potential. The Cerchar Abrasivity tests were performed over both sawn and rough rock surfaces. Simple linear regression analysis was performed to establish possible correlations between Cerchar Abrasivity Index (CAI), LCPC Abrasivity Coefficient (ABR) and other physical properties of rocks including UCS and BTS. The validation of developed equations was done by using 95 % confidence interval limits. The work done shows that selected sedimentary rocks from Western Salt Range have low to medium abrasiveness.
