Abstract: Loads and the environment are coexistent to concrete structures. The durability of concrete structures under load and environmental attacks simultaneously were elaborated, including carbonation, freeze-thawing, chloride penetration and sulfate attack. Conclusions can be obtained that the durability of concrete structures under imposed loads is worse than those without loads. The stress imposed on concrete members may promote or prevent the development of the internal micro-cracks in concrete. Because the tensile stress makes microcracks widen, the concrete corrosion will be accelerated, and the service life of concrete structures will be shortened. On the contrary, compressive stress will make concrete more dense and the concrete corrosion decline. Therefore, load is one of the important factors that can not be ignored in the study of concrete durability.
