Monitoring steel corrosion in reinforced concrete beams with variable crack widths under sustained load

This work reports on the investigation of steel corrosion behavior in 1000 mm in length reinforced concrete beams under sustained load, aiming to define a feasible experimental protocol for corrosion monitoring. The beams were subjected to wetting (5% NaCl for corroding cases and tap water for control ones) and drying cycles. Generally applied...

The influence of cracks on chloride-induced corrosion of reinforced concrete structures - development of the experimental set-up

Chloride-induced corrosion of steel reinforcement is one of the major threats to durability of reinforced concrete structures in aggressive environmental conditions. When the steel reinforcement starts to corrode, structures gradually lose integrity and service life is shortened. Cracks are inevitable in practice and they facilitate ingress of...
