Determinación de la deposición de iones cloruros y comportamiento de la velocidad de corrosión atmosférica del acero bajo en carbono en la línea costera de la parroquia crucita fase 3

Abstract

One of the main impacts caused by the aggressive deterioration of metallic and reinforced concrete structures are the corrosive atmospheric agents, which give us a representation of the high contamination that exists in the Crucita parish of the Portoviejo canton. It is for this reason that we must consider the main agents that influence and affect the structures, such as temperature, relative humidity and wind speed. This is the last phase of the first annual study carried out in the Crucita parish, Portoviejo canton, in which it was determined that there is a high level of corrosive aggressiveness due to the presence of a coastal atmosphere. In order to develop this study we used six wooden supports, which were built by the thesis students of phase 1, the supports were constituted at the beginning by 15 steel plates, in the course of the research were left for the development of phase 3 with 9 carbon steel plates which help us to identify how the marine environment affects the physical properties, i.e. allows us to show the wear on the plates due to oxidation and corrosion caused by the sea air. The antiseptic fabric sensors were located three cloths for each wooden support, built previously, obtaining the results of the monthly deposition of chloride ions that exists in each exposure zone, these elements provided the information of the first and second phase of the work, the data were taken monthly to each one of the sensors where phase 3 is the culmination of the project planned for 1 year of study. In the present investigation it was determined that the corrosive aggressiveness of the atmosphere in the Crucita parish is in the C5 category. It was also evidenced that there is a high degree of exposure of chloride ions, April being the month with the highest aggressiveness considering the values obtained in the year of study.
