To simulate this cyclic process, different salt solutions were designed according to the main precipitated components. Sandstone specimens taken from Longshan Grottoes were soaked in these solutions for 48 h and then placed in a simulated environment with temperature and humidity changes for 5 cycles (50 h) to study the effects of hydrochemical, temperature and humidity changes on the sandstone. Physical indexes, such as mass, wave velocity, surface hardness and tensile strength, of the rock samples were measured every three cycles, and the damage characteristics and mechanisms of the sandstone were discussed based on SEM and XRD test results. The results showed that the macroindicators and microstructures of the samples gradually decreased with increasing number of cycles. 2023-08-25T03:17:33Z 2023-08-25T03:17:33Z 2023 Book https://link.springer.com/article/10.1186/s40494-023-01021-3 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8942 en application/pdf Springer
