Abstract: Hydraulic lime is widely used in the restoration of historical buildings and geotechnical heritages due to its excellent performance and strong affinity with cultural relics. This paper introduces the preparation and properties of hydraulic lime, and summarizes the macroscopic performance changes of hydraulic lime in three types of corrosive environments: acid, alkali and salt, the performance improvement after modification and the microscopic deterioration mechanism, aiming to reveal the mechanism of the corrosion behavior of hydraulic lime. The research shows that salt environments cause the most damage to hydraulic lime; acid environments are second; and alkaline environments are the least. The durability of hydraulic lime can be improved by lowering the water cement ratio, adding volcanic ash materials and incorporating modifiers to improve the hydraulic lime generators, porosity and micro-morphology. Finally, the deficiencies of the research on hydraulic lime at this stage are pointed out, which provides reference and enlightenment for the research and development of hydraulic lime to deal with the actual environmental problems and new building repair materials.
