How To Prevent Corrosion In Concrete - Surtreat Solutions
Corrosion in reinforced concrete is one of the main concerns when talking about reinforced concrete structures. Typically, the reinforcements embedded into the concrete are protected by the high pH environment of the Portland cement around the reinforcements, which prevents corrosion from occurring (typically with pH levels around 12.5 or higher).

concrete corrosion Topic
Corrosion occurs when the protective layer in concrete steel reinforcement is destroyed. Steel in concrete is usually protected against corrosion by the high pH of the surrounding portland-cement paste. Cement paste has a minimum pH of 12.5, and steel will not corrode at that pH. If the pH is lowered (for example, to pH 10 or less), corrosion may occur if …
