Corrosion Mechanism, Prevention & Repair Measures of RCC Structure
Reinforced concrete structures are commonly used in construction due to their durability and strength. However, they are also susceptible to corrosion due to environmental factors such as moisture, oxygen, and chemicals. Here are the corrosion mechanisms, prevention, and repair measures for RCC structures:
Corrosion Mechanism:
Carbonation: Carbon dioxide in the atmosphere reacts with the concrete, reducing its alkalinity and causing corrosion of the reinforcing steel.
Chloride Attack: Chloride ions penetrate the concrete and reach the reinforcing steel, causing corrosion.
Acid Attack: Acidic substances such as industrial emissions or acid rain can corrode the reinforcing steel in RCC structures.
Prevention:
Concrete Cover: Adequate concrete cover can protect the reinforcing steel from exposure to environmental factors.
Use of Corrosion Inhibitors: Corrosion inhibitors can be added to concrete to reduce the corrosion rate of the reinforcing steel.
Cathodic Protection: A cathodic protection system can be installed to protect the reinforcing steel from corrosion by providing a low-voltage current that prevents the flow of electrons from the anodic to the cathodic areas.
Proper Maintenance: Regular inspection, cleaning, and repair of damaged areas can prevent corrosion from spreading.
Repair Measures:
Removal of Corroded Concrete: The corroded concrete and reinforcing steel are removed and replaced with new materials.
Electrochemical Realkalization: This method involves applying a high-pH solution to the corroded area, which helps to restore the alkalinity of the concrete and prevent further corrosion.
Surface Coating: Applying a protective coating to the surface of the concrete can help prevent further corrosion.
Corrosion Inhibitors: Corrosion inhibitors can be injected into the concrete to prevent further corrosion of the reinforcing steel.
Overall, it is essential to take preventive measures to protect RCC structures from corrosion and to regularly inspect and maintain them to prevent further damage. Proper maintenance, including timely repair of any damages, can extend the life of the structure and ensure its safety and durability.
