An Experimental Review of Effect of Sea Water on

A large number of structures are exposed to sea water either directly or indirectly. Therefore, this research work seeks to investigate the effect of sea water during mixing and curing on compressive strength of concrete. The necessity of this research work is that, commonly water used for concreting is water from boreholes which contains number of salts and hence we are testing it for extreme ...
