Potential measurements of the cylindrical tubes were carried out, so as to follow the aging process effect. The corresponding mean values are included in Table 1.Table 1: Potential test tubes corrosiontime (months) 2 4 6 8 10 11Ecorr (mV) 298 375 462 512 560 620According to the registered values and the test tubes physical states which became ochre with longitudinal fissures, it was estimated that the test tubes reinforcement was corroded.It is necessary to remark that to perform the realkalization technique。 mon concrete: %, water: %。 cover thickness: 20 mm。guez et al., 1993).2 Determination of the presence of concrete carbonation by phenolphthalein test, Sturm y .

Results and Discussion.To carry on the first test, six tubes were buried in the areas under study for 3 years. The carbonation test achieved showed that the carbonation fronts have a mean percentage of 5 mm in edges and 10 mm in corners.The photo depicts a prismatic test tube after the application of the phenolphthalein test.The photo shows a test tube to which the phenolphthalein test has been applied.The potential values of tubes 100 and 250 mV were registered. Those values indicate a very low corrosion probability from the qualitative point view. Bearing these data in mind, a quick aging technique was applied to test tubes. It was necessary to build cylindrical tubes with the following dimensions: diameter: 300 mm, length 400 mm。n Department San Juan ProvinceArgentina. Nevertheless, only one was chosen to be repaired applying the above mentioned technique. Preliminary and detailed inspections (Feli b) on concrete, since it generates expansive oxides in the steelconcrete interface causing fissures and spalling and c) in steelconcrete adherence.In Great Cuyo Region, mainly in San Juan and Mendoza provinces Argentina, there exist wi
