Compressive strength and tensile strength of rocks at sub-zero temperature

Abstract

The present paper deals with the uniaxial compressive and tensile behaviour of Chunar sandstone and Makrana marble at sub-zero temperature (0°C to -20°C) in dry and wet conditions. It was found that uniaxial compressive and tensile strengths of these rocks increased with decrease in temperature below 0°C. Both strengths in general and tensile strengths in particular of wet rocks increased more rapidly in comparison to dry rocks.
