Title: Limitation of the Water Content of Concrete as a Repair Method for Reinforcment Corrosion in Carbonated Concrete
Author(s): P. ScheiBl and R. Weydert
Publication: Special Publication
Appears on pages(s): 519-534
Keywords: Carbonation; coatings; concretes; corrosion; repairs.
Abstract:After damage due to reinforcement corrosion in carbonated concrete, repair principle W - limiting the water content of concrete - as specified in the Draft Recommandation for Repair Strategies for Concrete Structures Damaged by Reinforcement Corrosion (l), can be applied in the repair of concrete compo-nents. The repair principle involves sealing the concrete surface with a suitable surface protection system after exchanging and reprofiling the damaged concrete areas. As a result the water content in the concrete shall be reduced to such an extent as to bring the corrosion process of the reinforcement to a standstill. The effectiveness of surface coatings as corrosion protection systems has been investigated on carbonated concrete specimens using the simultaneous measurement of corrosion rates and electrolytic concrete resistivities.
