Seawater concrete refers to concrete mixed using seawater instead of fresh water and often incorporates corrosion-resistant reinforcements or specialized cementitious materials. This approach is particularly advantageous in remote coastal areas where fresh water is scarce but seawater is abundant. The primary mechanism of seawater in concrete involves the interaction of chloride ions from the seawater with the cement paste and reinforcement. While chloride ions are typically deleterious due to their corrosive effects on steel reinforcement, when used with corrosion-resistant reinforcements or in controlled environments, seawater can effectively participate in the hydration process without detrimental effects.
