Research status of material damage and deterioration mechanism of static/dynamic mechanical properties of long-age concrete
With the increase of service life,the problem of insufficient durability of concrete is becoming increasingly prominent,which has become the main reason for engineering failure.The influencing factors and mechanisms of concrete deterioration and damage are sum-marized,including carbonation,freeze-thaw,multi type corrosion medium and multi factor coupling.The deterioration law of durability factors on static and dynamic mechanical properties of concrete materials is summarized.Finally,it looks forward to the focus of future concrete durability research,which should strengthen the research on modern concrete deterioration mechanism,the research on concrete durability with changesin raw material composition,and the research on the mechanism of dynamic mechanical property deterioration of long-age concrete under intermediate and high strain rate loading.
