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

Amin Jamshidi, Luís Sousa

Short summary

Point load index (PLI) better predicts uniaxial compressive strength (UCS) in compact granites (R²=0.82) than in porous travertines (R²=0.65), due to higher data dispersion in travertines.
