Estimation of Compressive Strength of Rocks Using Non-destructive Testing Methodsd rebound number (RN) on A, B, C scales, RN in A, B, C scales and .d. A simple regression study showed good outcomes, with all the regression coefficients being greater than 0.80 and the highest being 0.97 for the estimation of UCS using the ratio of RN (A scale) and .d. This study can be used as a tool for the preliminary estimate of UCS.
