Electro active repair of concrete: Innovation for increased repair durability

Many repairs of chloride induced corrosion in practice fail within 10 years due to chloride remaining after cleaning the steel, causing corrosion re-activation. An improvement of conventional repair was invented, Electro Active Repair, that electrochemically removes chlorides. After concrete removal, a temporary electrolyte and anode are...

The steel-concrete interface

Although the steel–concrete interface (SCI) is widely recognized to influence the durability of reinforced concrete, a systematic overview and detailed documentation of the various aspects of the SCI are lacking. In this paper, we compiled a comprehensive list of possible local characteristics at the SCI and reviewed available information...

Electro active repair of concrete for improved durability of conventional repair

Chloride induced reinforcement corrosion is increasing due to aging of concrete infra structure. Conventional repairs have poor durability and many fail after less than 10 years. For conven tional repair chloride contaminated concrete is removed, steel is cleaned and new concrete is applied. Leaving chiorides, eg. in pits, corrosion may re...
