Study on durability of concrete curing agent consists mainly of solidified soil impermeability, frost resistance, resistance to dry and wet cycle ability, also included in the special fields such as corrosion resistance, erosion resistance performance. While the mechanical properties of concrete curing agent with high, but the content of hydrophilic clay minerals in soil is high, so the durability of solidified soil has great influence. Tests prove that, the influence factors of solidified soil mechanical properties. Durability of solidified soil also has a significant impact on. In the performance of solidified soil durability test, study more soil curing agent is the anti permeability and frost resistance of solidified soil. Research shows that export door, solidified soil with higher impermeability frost resistance, but poor performance, which limits the application field of concrete curing agent and regional. Because of the durability of the concrete curing agent is a basis to achieve technical and economic index of engineering optimum design. Therefore, the construction technology improvement concrete curing agent formula or improvement of solidified soil, in order to improve the durability of solidified soil is one of the directions for future research.
