Steel rebars represent a main component of reinforced concrete and their quality largely influences the structural and long-term behavior of structures. A quality control plan is established to monitor the supply on the site and the performance of the rebars. Generally, the tensile strength complies with the general requirements, due to the Tempcore production process, that forms a hard tempered martensitic layer in the outer shell of the rebars. On the other hand, the high number of MnS inclusions and the increased corrosion susceptibility of the steel rebar’s outer layer as compared to the ferritic-perlitic microstructure of the steel rebar cores, requires a careful monitoring of the steel rebar’s durability, to attain 100 years of service life of reinforced concrete infrastructures.
