Cathodic Protection of Steel in Concrete by Surface Painting

Cathodic Protection for steel inside concrete: The corrosion of steel in concrete occurs as a result of chloride attacks or carbonation of a concrete surface and incursion into the concrete until it reaches steel, which

The Incipient Anode Effect

TeamCivil Concrete, Durability

The Incipient Anode Effect When an area of steel is corroding under the influence of chloride contamination, steel is dissolving causing the formation of iron ‘ions’, tiny charged particles of iron. Simultaneously, electrons are released

Selection of Antifreeze Admixtures

TeamCivil Concrete, Durability

An antifreeze admixture is selected according to the design temperature at which concrete is supposed to harden. If the temperature rises above the design value or even becomes positive as the concrete is cured, its
