Abstract: This paper reviews the current status and progress of research on the durability of concrete under multi-factor environments. It primarily explores the erosion mechanisms of concrete under the combined effects of chloride and sulfate ions, the impact of combined load and salt environments on concrete durability, the corrosion effects of stray currents on concrete structures, and the influence of high hydrostatic pressure on concrete durability. The study summarizes the migration behavior and interactions of different ions within concrete, analyzes the mechanical properties and corrosion patterns of concrete under various environmental and load conditions, and elaborates on the effects of stray currents and high hydrostatic pressure on the microstructure and permeability of concrete. Finally, it provides recommendations and outlooks on future key research directions and the practical engineering applications of durability research outcomes in this field.
