Metallurgical Environment Durability Analysis Of Concrete Structures

Reinforced concrete structure will deteriorate and damage because of the natural environment and the long-term usage. But in China the fact is that people think much of the strength but neglected the durability of concrete, caused large numbers of safe trouble take place. It will affected the construction and the development of the our country. Own to this, many expert apply themself to the research of the durability of concrete. At the same time, they attach importance to the theoretics but neglected the practice.In this paper, the author selected the specially corrosion structure. First the article carries on the theory analysis to the concrete durability and the service life predication; Then the present condition of the structure is investigated and the samples are taken back; On the basis of examining and analyzing the resistance of a building, its security and reliability are evaluated. As a result, the structure must be repaired and we should research a new repaird material.The author experimented with the sample and investigated why the structure was destroyed. Ture to the analysis result, a new repaird material (B2) was developed. At the end of the paper , The model of the service life predication was set up and this new repaird material is very successful.
