Since concrete structures are often exposed to different aggressive environments, they require high quality protection systems. Reinforced concrete structures are built to serve many generations to come. However, concrete faces many threats of natural deterioration, damage and reinforcement corrosion.
2 Most Common Causes of Concrete Damage and Reinforcement Corrosion
The two most universal causes of reinforcement corrosion and concrete damage are carbonation and chloride attack. The faster carbon dioxide or chlorides penetrate the concrete, the sooner the passive layer around the reinforcement bars is destroyed and the corrosion process is initiated.
Understanding the root cause of steel corrosion determines the most effective repair and protection strategy. To ensure long-lasting durability, an appropriate maintenance strategy should be followed by owners and their construction management.
