| Abstract: | To illuminate the load effect for the structure durability,the durability research of concrete structures under load and material influence factors is introduced,which included carbonation,sulfate attack,chloride penetration and freeze-thawing.The investigation shows that the concrete structures durability are significantly lower under the sustained load than unload.The conclusion is get that the sustained load is the important factor in the concrete research.At the same time,the research of carbonation dep... |
