Sandstone intact rock specimens are tested to study their point loading strength, while the microscopic properties of the tested specimens are analyzed in thin sections to determine the mineral composition, grain size, cement and contact modes between grains. The intrinsic influence of petrographic characteristics on measured strength is evaluated using regression analysis among the obtained laboratory data.
