Study of Corrosion in Reinforced Concretes with Different Water to Cement Ratios at Splash zone

Concrete structures in aggressive environments greatly suffer from corrosion which causes a premature failure in their life span. Persian Gulf region is one of the most aggressive environments in which concrete structures need further attention in order to increase their durability and serviceability as well. In the present investigation the half-cell potential and corrosion resistance of rebar embedded in concrete with different water to cement ratios exposed to splash zones in Qeshm Island for 18 month was studied. The results demonstrated that concretes with lower water to cement ratio perform better in terms of corrosion protection and process retardation.
