Deterioration of Concrete Structures and Some Relevant Issues

Abstract

Performances of concrete structures should be decreased with time due to some mechanisms of deterioration such as chloride attack, carbonation of concrete and alkali aggregate reaction. Considering the establishment of an appropriate maintenance system for such structures, there are many problems to be solved. In this paper, deterioration cases of concrete structures are outlined, followed by the explanation of some investigations to build the maintenance system and remained issues, regarding mainly the problem of steel corrosion in concrete.
