RISExperimental Study on the Compressive Strength and AE Characteristics of High-Temperature–Treated and LN<sub>2</sub>-Cooled Sandstone
Publisher: ASCE
Abstract: Liquid nitrogen (LN2) fracturing is beneficial to the development and utilization of geothermal energy. In this paper, red sandstone was heated from room temperature to different temperatures (25°C–800°C) and then cooled ...
Failure of Frozen Sandstone under Uniaxial Compression with Interpretation of Pressure Melting of Pore Ice from Electrical Resistance
Publisher: American Society of Civil Engineers
Abstract: Understanding the failure process in frozen porous rock is of great importance to both geomorphology research and engineering design in cold regions. The mechanical behavior of frozen porous rock has its own particularity ...
