Frost Damage in Tight Sandstone: Experimental Evaluation and Interpretation of Damage Mechanisms

Low-porosity tight rocks are widely used as building and engineering materials. The freeze-thaw cycle is a common weathering effect that damages building materials in cold climates. Tight rocks are generally supposed to be highly frost-resistant; thus, studies on frost damage in tight sandstone are rare. In this study, we investigated the deterioration in mechanical properties and changes in P-wave velocity with freeze-thaw cycles in a tight...
