The challenge of structural durability.
Structural pathologies represent a silent risk to your property. Carbonation of concrete Chloride attack is the main culprit in reduced durability. Therefore, understanding these processes is crucial to preventing serious breakdowns.
Understanding carbonation
Concrete naturally has a high pH. This keeps the steel reinforcement passivated and protected against oxidation. However, carbon dioxide penetrates the pores of the concrete over the years. Consequently, the pH drops drastically and the steel becomes depassivated. In addition, corrosion of the reinforcement generates expansion and causes spalling of the concrete.
The severe impact of chlorides
On the other hand, chloride attack is even more aggressive in coastal regions. For example, the sea spray that affects the structures of Brave Beach It accelerates the oxidation of steel immediately. Unlike carbonation, chlorides attack the steel in specific locations. In this way, they create what are called pits, which reduce the cross-sectional area of the reinforcement without warning.
Standardization and prevention
To mitigate these problems, we strictly follow the parameters of NBR 6118. This standard establishes clear criteria for nominal concrete cover for each environmental aggressiveness class. Therefore, the structural design must provide for concretes with low porosity and high strength. Furthermore, preventive maintenance avoids exorbitant costs associated with structural reinforcements.
Warning signs: cracks and corrosion
Have you noticed diagonal cracks or rust stains on your ceiling? Often, these signs indicate that corrosion has reached a critical stage. Consequently, the structure loses its load-bearing capacity and may experience differential settlement. For example, a lack of waterproofing exacerbates these problems. Therefore, diagnosing the problem early is the only way to save the integrity of your building.
