Corrosion in reinforced concrete
- Corrosion protection coatings for reinforced concrete structures
- Corrosion processes in concrete structures start when aggressive species such as water, oxygen, seawater, and CO2 reach the surface of the rebar.
- Appearance of cracks at the concrete structure surface occurs due to a formation of voluminous iron corrosion products.
- Corrosion protection coatings with sacrificial effect are using in order to provide an extra barrier that isolate the rebar from environment.
Basic and applied research in concrete structures
- Real-time monitoring DC/AC basis
- Characterization of the aggregates and admixtures based on reliability and damage evolution
- Coatings and inhibitors design and efficiency by using electrochemical techniques
Corrosion under hydrodynamic conditions Fow loops with sampling for AC system
- Internal corrosion is observed due to chemical attack on the interior of the pipeline from aggressive species such as water, sodium chloride and CO2.
- Hydrodynamics conditions inside the pipeline can accelerated considerably the corrosion attack due to higher diffusion of aggressive species and presence of erosion corrosion.
- Corrosion inhibitors with different chemical structures are used for preventing internal corrosion.
