ABSTRACT
ABSTRACT: Reinforced concrete is a leading structural building material. This is due to its unique physical and mechanical properties, high raw material base for the production of and relatively simple technology and preparation. However, with the passage of time in reinforced concrete structures evolving process of destruction. The article describes the main causes of these processes. Describes the main types of corrosion of concrete and corrosion classifications. In the second part of the article describes estimation of RC construction durability according to diachronic model. The modern market of construction materials becomes wider by development of building sector. One of the prevailing materials used in construction is RC concrete. It is used both at monolithic construction and at manufacturing of complete prefabricated units at factories. As any constructional material concrete is subject to corrosion. That’s why we should deal with present day regulatory framework of designing reinforced concrete and find out by what types of corrosion it is affected.
