Damage Test And Assessment Of Durability On Concrete Structure

The concrete structure has been one of the most famous shapes in building construction as Potelan cement came out. For about one hundred years, people has been working on the technology of concrete examination in order to grasp the whole circumstances of inner and outer damage about concrete structure in all environment and assess the durability of concrete construction and make concrete construction serve the society safer and more economical.In this paper the mathematic model of a dock is examined at first, the result is compared with the date come from the test. Furthermore, the material of the dock has been tested by some means in order to provide some date for assessing the dock.Secondly, the paper carefully analyses the factors that influence the durability of concrete construction from some effects, such as carbonization, chloride, anti-freeze, anti-osmosis, alkali, erosion of reinforcing-bar, etc., and provide some methods to improve the durability of concrete construction.At last, the paper put forward a kind of method, called arrangement method, in order to assess the durability of the concrete construction more accurately and more conveniently.
