Research on Ordinary Concrete Durability

This paper introduces the common concrete durability research background of the status quo, summarizes the corrosion resistance of concrete under the background of the main influence factors. The corrosion types and corrosion mechanism of concrete are discussed, including the corrosion mechanism of concrete base material of cement, steel corrosion mechanism and corrosion mechanism of reinforced concrete structures. From the research and the analysis of the structure formation of ordinary concrete, summarizes the common strength grade of concrete high performance-based approach.
