IMPACT OF CORROSION OF REINFORCEMENT IN

2016-10-22  Reinforced concrete design must include adequate step for prevention of concrete and rebar corrosion due to a variety of corrodent. Field experience has shown that concrete cover in itself does not provide an adequatesolution except in mild exposure. A number of measures are available for corrosion mitigation in design of reinforced concrete. The ultimate solution in design shrinking an optimum balance in developing a cost-effective method for enhancing the safe service life of this structure. The anticipated severity of the corrosive

Marine Concrete Webinar – Australasian Corrosion

Reinforced concrete structures in marine environments can be very durable and may not suffer significant chloride-induced corrosion of steel reinforcement even when well beyond their design lives. Condition surveys of several reinforced concrete marine structures up to 100+ years of age have revealed no significant reinforcement corrosion.
