Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-1720
... ABSTRACT: Triaxial compression experiments were performed on two pure, dense, high strength and low-porosity calcite rocks, limestone and marble. Intact samples from crystalline limestones (“Mesaio limestone”) and marbles (“Kavala marble”) were subjected to conventional triaxial testing using...
