Concrete Exposed to Seawater – Effects and Preventions

The concrete structures built in marine conditions are always exposed to seawater either directly or indirectly. The coastal and offshore structures are always in contact with seawater and there are number of physical and chemical deterioration processes takes place. So, Concrete structures effected by seawater requires special attention.

Suitability of sea water on curing and compressive strength

Divergent options exist on the effect of sea water as mixing water in concrete. As sea water contains various types/amounts of dissolved salts that can react with reactive aggregates, sea water should not be used even for plain concrete if the aggregates are known to be potentially alkali reactive. It is reported that the use of sea water for ...

Effect of Water Impurities on Concrete Strength

Water Impurities and their Effect on Concrete Properties. The effect of various properties on the concrete properties are explained below: Effect of Suspended Particles in Water on Concrete Properties. If the mixing water contains suspended particles in an amount up to 0.02 percent by weight of total water used in concrete, it will not affect the concrete properties.
