Before revision: Considerable efforts have therefore made in the last decades in order to define useful models describing the degradation processes affecting reinforced concrete structures, to be used during the design stage in order to assess the material characteristics and the structural layout of the structure.. Service life of a reinforced concrete structure 500px|Initiation and propagation periods of steel rebar corrosion in a reinforced concrete structure Initially, the chemical reactions that normally occur in the cement paste, generate an alkaline environment, bringing the solution in the cement paste pores to pH values around 13.
