Effect of Water Impurities on Concrete Strength

The concrete of very lower water/cement ratio facilitates this requirement of sulfate resistance. The salt content in sea water reduces the concrete strength by an amount of 10 to 20 percent. More than strength factor, the corrosion of the reinforcement is considered as the adverse effect. The chlorides are the main cause of corrosion.
