“…The investigation and modeling of the effect of cooling on the mechanical properties of bars produced through the TempCore process have received increasing attention in the last two decades in the scientific and technical community, such as, for instance, in the works of Martinez, Nino et al, and Nikolaus and Papadimitriu . The final ambition is in most of the cases to use the developed models to set up the process parameters in order to optimize the mechanical properties of the final rebar …”

The production of steel reinforcing bars for civil engineering is investigated by means of finite element model-based simulation. The aim of this study is to predict the internal structures of steel bars after treatment through the TempCore process by using a finite element method. Moreover, a model for the prediction of final mechanical properties of the bars produced by means of this process has been constructed and validated with real industrial data. Highlights FEM was used to simulate the thermal evolution of bars in the TempCore cooling stand. A predictive model of bar final macrostructure was constructed and validated. A predictive model of bar final mechanical properties was constructed and validated. An average percent error for prediction of tensile strength less of 1.54% was got. An average percent error for prediction of yield strength less of 2.23% was got.

“…The first solution simulates saline / marine environments [4,11], while the other two simulate concrete pore environments in mild and aggressive environmental conditions, respectively [1, 4, 7-9, 11, 28]. This simulation is based on the fact that Ca(OH) 2 crystals can occupy approximately 20%-25% of the cement paste volume [28]. After the necessary metallographic preparation, the microstructure of the specimens (cross-sections) was examined by SEM (Scanning Electron Microscopy)/EDX (Energy Dispersion X-ray spectroscopy) (JeoL JSM 6510 LV SEM / Oxford Instruments X-Act EDX).…”

Accelerated corrosion performance of AISI 316L stainless steel concrete reinforcement used in restoration works of ancient monuments

The accelerated corrosion performance of AISI type 316L stainless steel rebars in solutions simulating concrete exposed to various environments was studied by means of cyclic polarization, before and after a four month salt spray test. B500A structural steel rebars were also tested for comparison reasons. Although 316L showed some susceptibility to localized corrosion during polarization in saturated Ca(OH)2 containing 3.5 wt.% NaCl, four months of salt spraying did not significantly affect its polarization behavior. Salt spraying for 4 m did not have any significant effect on the macrostructural state of 316L reinforced concrete.
