The consequences of fires on cultural heritage building and monuments can be deleterious,
as historic and recent cases demonstrate. In particular, devastating fires have ravaged stone …

This paper reports the variations of thermal conductivity, thermal diffusivity and heat capacity
of sandstone after high-temperature heating. Experiments were carried out to test the …

The physical, mechanical and morphological properties of a rock undergo substantial
change when exposed to the extreme temperatures that are encountered in processes such …

Heating at high temperature will make the tensile strength of sandstone change due to the
loss of water and minerals and the effect of thermal stress. In this paper, the sandstone …

In this study, a PFC 2D model based on the XRD component distribution of the granite
specimen was built by the discrete element method, and the model parameters were …

This paper experimentally studies the variation of pore characteristics and mechanical
properties of sandstone at different temperatures (from 25° C to 600° C). The results show …

Experimental investigations of the effects of elevated temperature on microstructural,
mineralogical, physico-mechanical and elastic properties of rocks were carried out to …

Studies conducted by several researchers suggest that a large variance exists in the
morphological integrity of rocks when subjected to thermal treatment. The extent of thermal …

Improving permeability is the crucial mechanism for further enhancing oil and gas recovery
of ultra-low permeability reservoirs. To investigate the temperature sensitivity and stress …

Thermal cracking in rocks can cause a significant increase in permeability, which is of great
significance for enhancing the oil recovery of ultra-low permeability reservoirs. To evaluate …
