混凝土结构的使用荷载与使用环境是共存的,从渗透性、抗碳化性能、抗冻融性能、抗氯离子和硫酸根离子侵蚀等方面阐述了荷载对混凝土耐久性的影响,得出一致结论:施加荷载的混凝土构件要比无荷载作用的混凝土构件耐久性水平低,荷载是耐久性研究中不可忽视的因素之一。
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.Therefore, load is one of the important factors that can not be ignored in the study of concrete durability.
