Study on the durability of solidified mud under chloride and dry-wet coupling
Published 2025-01-01“…It was found that the hydration products such as hydrated calcium silicate gel ( C-S-H ) and calcium hydroxide crystal ( C-H ) in the solidified mud samples under the coupling of chloride erosion and dry-wet cycle were reduced, and more pores and cracks appeared. Under the same number of dry-wet cycles, the higher the concentration of sodium chloride solution, the more serious the micro-damage inside the sample. …”
