This article, is part of a long time ICCET investigation programs studies the variation of the mechanical resistance to flexotraction 1: 3 normalized mortar with 1 x 1 x6cm dimension, using sulphate-resistent portland cement mixed with 15-35-60 and 70% parts of a furnace slag, a fiy ash or silica sand. The samples were submitted to the action of AS.T.M. artificial sea water and filtered potable water during several time periods (3 years for the first and second addition and 1 year for the third) after the cured period (1 day at 100% R.H. and 21 days inside filtered potable water). The evolution of the ionic concentration of the aggressive solutions were studied and also the new phases formed with its new structural composition. Finally, and account is given of the researches and first results about the behavior of the mortars and concretes made with two different industrial cements and submitted to the natural sea water at a selected area of the marine Huelva-Port.
