DURABILITY OF CONCRETE STRUCTURES UNDER LOAD
Loads and the environment are coexistent to concrete structures. The durability of concretestructures under load and environmental attacks simultaneously were elaborated, includingcarbonation, freeze-thawing, chloride penetration and sulfate attack. Conclusions can beobtained that the durability of concrete structures under imposed loads is worse than thosewithout loads. The stress imposed on concrete members may promote or prevent thedevelopment of the internal micro-cracks in concrete. Because the tensile stress makes micro-cracks widen, the concrete corrosion will be accelerated, and the service life of concretestructures will be shortened. On the contrary, compressive stress will make concrete moredense and the concrete corrosion decline. Therefore, load is one of the important factors thatcan not be ignored in the study of concrete durability.
