Tensile strength and brittleness of sandstone and granite after high-temperature treatment: a review

High temperature may cause damage to microstructure of rock, which has a significant effect on rock behavior. In this study, the changes in tensile strength and brittleness of sandstones and granites with temperature and corresponding mechanisms are summarized and analyzed based on an extensive review of literature. The results show that as thermal treatment temperature increases to 400 °C, the tensile strength of sandstones changes with two...
