Spatial variability and quantitative characterization of thermal shock damage in sandstone under different cooling temperatures Open
This research employs micro-CT scanning technology to analyze the porosity, pore fractal dimension, and spatial variability of sandstone preheated to 600 °C and subsequently cooled in water at varying temperatures (20 °C, 60 °C, 100 °C). T…

Experimental Study on the Effect of Thermal Shock on Physical and Mechanical Properties of Limestone Open
Thermal shock is the physical process of rapid cooling of a hot object. The physical and mechanical properties of rocks that have undergone thermal shock will change. This variation can be applied to the development of geothermal in limest…
