Abstract and Figures. Steel corrosion is the main source of damage and early failure of reinforcement concrete structures that in turns create huge economical loss and creating environmental ...
The corrosion of the steel in concrete is an electrochemical process. When there is a difference in the electrical potential along the steel reinforcement in concrete, an electrochemical is set up. In the steel, on part becomes the anode and the other part will form as a cathode. This system is connected by means of an electrolyte.
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 …
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).

Polymeric Fibre – The usage of polymeric fibres in concrete can prevent steel from corrosion. Proper Workmanship – Ensure that the concrete should be poured with proper compaction without bleeding and segregation ( Honeycomb )to avoid the voids happening on the surface. Hope you enjoyed the topic. Happy Learning 🙂.
Chloride corrosion of reinforced concrete Author: Efremov D.N. It has long been recognized that chloride ions play a major role in the corrosion of steel in concrete. The chloride ions may originate from the ingredients of the concrete mixture, or may diffuse through the hardened concrete. Most building codes attempt to control corrosion ...
6) Temperature: Increase in temperature increase the diffusion of O2 & increases the Corrosion. Above the temperature loss of dissolved O2 exceeds and corrosion decreases.
