Resumen:
Foundations are a fundamental part of the structural framework in buildings, according to the final dimension and weight, it changes impact in loads transmition to the ground, and the structure design, as its mechanism of operation along with its useful life. However, the deterioration of the concrete or metal surface presented in the medium upon contact with the subsoil many times has not been considered. It depends on the characteristics and components of the site, as the solid surface, and chemical composition, of the structural elements. They can be altered by salty ingredients, modifying the structural properties with which it has been designed to support the building. This research has been carried out to analyse the characteristics on the surfaces of the materials commonly used for the production of foundations in buildings (Steel, concrete, and wood), which are in principle underground, presenting various components. Experimental and theoretical analysis of surfaces is carried out on elements of concrete, steel, and wood, exposed in an aqueous medium with and without salt, observing the microscopically change, fractal dimension, and rugosity modifications on the surface. We found that the presence of saltwater tends to modify the fractal dimension and the specific surface area of concrete and steel majorly. For this case, the fractal dimension grows with corrosion and increase specific area too. We present a correlation for the three materials, which indicates that the presence of the salts significantly influences the roughness and porosity of the surface. These results may be used for resistance change with surface modification. © 2020, World Academy of Research in Science and Engineering. All rights reserved.
