This article studies the influence of addition of different quantities of slag and compares this with the addition of fine particled silica sand. The mortar samples (1:3) of 1 x 1 x 6 cm —prepared with a sulphate-resistent portland cement, mixed with a selected slag and with silica sand were subjected to the action of artificial sea water ASTM and to a saturated plaster disolution for different periods of time (3 years for the first and 1 year for second ones). The performance of the following factors was determined: the mechanical resistence (to flexotraction), the Koch-Steinegger corrosion coefficients, the structural composition of the new solid phases formed in the cured medium and the preservation-attack. The following were also examined: the hidrated-attacked cement paste and its mixes with the slag and the silica sand taken from the mortar sample, and the variation in concentration of Ca (II) and Mg (II) ions. The performance in mechanical resistence of samples of mortar measuring 4 x 4 x 16 cm and of concrete measuring 10 x 10 x 40 cm were also studied in this way. These samples were made with the aforementioned cement and subjected to the action of the said disolutions for different periods of time (up till 5 years). Finally, an account is given of work which has been started on this subject at a selected area at the Autonomous Port of Huelva.
