Concrete problems due to sulfate compounds

Sulfate compounds, including sulfates, chlorides, commonly found in seawater, natural water sources, agricultural areas, groundwater, brackish water, and even in chemically-contaminated wastewater

Extended exposure of concrete to seawater can result in chemical reactions with sulfates, leading to potential damage both internally and externally within the concrete structure.

1. Chemical-related issues within concrete:

Chemical reactions generate new substances, causing expansion and deterioration of the concrete structure.

2. Physical issues on the exterior:

Salt deposits (efflorescence) or white stains can form on the surface of the concrete due to the presence of sulfates.

One of the significant challenges faced by concrete structures such as ports or bridges located in coastal areas and natural water sources is the problem of erosion caused by sulfates or saltwater. This natural occurrence, when left unaddressed for a prolonged period, can lead to detrimental effects. The formation of salt deposits on the concrete surface can result in cracking and corrosion of the internal reinforcement. To mitigate these issues and enhance the durability of such structures, the use of protective products that combat corrosion and reinforce the overall resilience becomes essential. By employing these measures, the lifespan of the structures can be extended, maximizing the utilization of Earth's resources and minimizing the generation of waste.
