Characterization of Uniaxial Compressive Strength and Point Load Index and Their Correlation in Compact and Porous Building Stones: Insights from the Effects of Stone Heterogeneity

The point load index (PLI) is a low-cost and rapid test widely used for the indirect evaluation of uniaxial compressive strength (UCS). However, its accuracy in predicting UCS may differ between compact and porous stones. This study investigated the performance of the PLI for UCS...
