Corrosión de armaduras en el hormigón armado en ambiente marino aéreo

Abstract: AGRADECIMIENTOSQuiero expresar mi sincero agradecimiento a Mª Pilar Alaejos, directora de esta tesis, por su dedicación y respaldo, por guiarme a lo largo de la investigación, y por creer en mí y en el buen fin de este trabajo. Gracias por reforzar mi autoestima en momentos clave y por hacerme creer que era capaz de conseguirlo.También quiero dar las gracias a la Dirección General del CEDEX, especialmente al Laboratorio Central de Estructuras y Materiales, por sus iniciativas para fomentar la formación de post… Show more

“…As reported by [8] for low-quality porous concretes, the carbonation velocity is V CO2> 9 mm/year½, therefore, the corrosion onset is 11 years and the propagation time is 44 years to 55 years of exploitation of these buildings. In this sense, [19] states that the onset of cracking is 6 years for carbon steels and that the time required for the corrosion damage to spread from 2% -12% is 16 years, therefore it is inferred that in 44 years the damage has spread much more.…”

“…The rupture of the passive layer is caused by the loss of the alkalinity of the concrete when it reacts with substances such as CO2 (carbonation) or when it is exposed to the presence of chlorides. When carbon dioxide penetrates concrete in the presence of moisture, a reaction occurs with the calcium hydroxide that composes the cement and forms calcium carbonate that eliminates the hydroxyl ions of the pore solution, with which the pH of the concrete is reduced to reach values less than 9, therefore the passive layer of the steel is disabled, and the corrosion process begins [14]. Carbonation deterioration happens more quickly when the reinforcing steel is not adequately coated.…”
