Chloride Penetration in Concrete: Why Coastal Slabs Fail and How to Slow It Down

Concrete /

Introduction Chloride penetration in concrete is the inward movement of chloride ions from the environment into the concrete and reinforcement area. In coastal areas, salt spray, moisture, and wet-dry cycles push chlorides into the concrete matrix. This can lead to corrosion of reinforcing steel and reduce the structure’s long-term durability. To slow chlorides down, choose
