Resumen
La corrosión por carbonatación es un fenómeno que afecta a los elementos de
hormigón armado sometidos permanentemente a concentraciones de dióxido de
carbono y humedad, como ocurre en el caso de los edificios de Santiago. El objetivo
principal de este trabajo es exponer la trascendencia de este proceso, primero,
mediante una revisión del estado del arte, y segundo, mediante la exposición visual de
los daños producidos en balcones de Santiago. Para ello, se presenta con amplio apoyo
fotográfico los casos más aleccionadores, de cerca de 200 balcones con daños
producto de la corrosión por carbonatos. Con esto, se comprueba la hipótesis de que
este proceso ha provocado daños, de manera extensiva a lo largo y ancho de la capital,
en edificios de distintas edades y emplazados en diversos sectores socioeconómicos.
Además, se realiza una clasificación de los tipos y grados de severidad de los daños,
para finalmente, proponer criterios para mitigar los efectos de la carbonatación a través
de la prevención, protección y reparación.
Corrosion by carbonation is a phenomenon that refers to the elements of permanently reinforced concrete carbon dioxide and humidity, as in the case of buildings in Santiago. The main objective of this work is to expose the importance of this process, first, by means of a review of the state of the art, and second, by means of the visual exhibition of the damages in the balconies of Santiago. To do this, consult with a wide photographic support the most instructive cases, about 200 balconies with damage caused by corrosion by carbonates. With this, the hypothesis is verified that this process has caused damages, of extensive way throughout the length and width of the capital, in buildings of different ages and located in diverse socioeconomic sectors. In addition, a classification of the types and degrees of severity of the damage is made, to finally propose criteria to mitigate the effects of carbonation through prevention, protection and repair.
