Thawing and Softening of Frozen Sandstone by Microwave Irradiation

The strength and hardness of rock are much higher at freezing temperatures than at room temperature. This results in high excavation costs and low excavation efficiency in frozen rock layers. This study proposes a novel way to thaw porous and water-bearing rock by microwave irradiation. It is applic...
