The corrosion mechanism of concrete under the coactions of stress and carbonation corrosion was discussed. The specimens were categorized into three types: non-stressed, bend-tensile stress and compressive stress. Carbonation of the specimens was accelerated. A multi-factor model forecasting the carbonation depth of prestressed concrete was constructed, introducing k wc and χ σ , which...

The durability experiments of prestressed concrete specimens in carbonation corrosive environments were carried out. The corrosion mechanism of concrete under the coactions of stress and carbonation corrosion was discussed. The specimens were categorized into three types: non-stressed, bend-tensile stress and compressive stress. Carbonation of the specimens was accelerated. A multi-factor model forecasting the carbonation depth of prestressed concrete was constructed, introducing k wc and χ σ , which describe the relationships between carbonation depth and concrete quality or strength or stress levels. The results show that the tensile stress and compressive stress are able to accelerate or slow down the concrete carbonation, respectively, and the larger the changes in stresses, the larger the changes in carbonation degrees. χ σ reflects the changes well. The compressive stress can control the development of concrete cracks, and eliminate the crack width, so the durability of the prestressed concrete structure is better than that of an ordinary concrete structure.
