Introduction 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. Composition of Seawater The 71% of …
Seawater Exposure on Durability of Concrete Seawater is a definite corrosive environment that affects the durability structure. The structure could be close to the sea, submerged in the sea or part of the structure could be exposed to the tidal waves.
Recent Evidence and New Preventive Measures in Regard to Disintegration of Mortar and Concrete in Seawater Attack on Portland Cement Concrete by Alkali Soils and Waters - A Critical Review 1966
Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. It normally refers to the duration or life span of trouble-free performance.
Concrete with a low water-cementitious ratio 0.40 or lower is more durable than concrete with a high water-cementitious ratio 0.50 or higher . Air-entrained concrete with a low water-cementitious ratio and an air content of 5 to 8 percent of properly distributed air voids will withstand a great number of cycles of freezing and thawing ...
The Romans made concrete by mixing volcanic ash with lime and seawater to make a mortar, and then incorporating into that mortar chunks of volcanic rock, the "aggregate" in the concrete. The combination of ash, water, and quicklime produces what is called a pozzolanic reaction, named after the city of Pozzuoli in the Bay of Naples.
