Se evaluaron las propiedades físicas de los agregados, continuando con la elaboración del diseño de mezclas del hormigón de control y probetas de hormigón con sustitución parcial de virutas de acero, a cada probeta se le realizó el ensayo de resistividad superficial y el ensayo de la resistencia a la compresión en un periodo determinado de 28 días de curado húmedo. Se efectúo la comparación entre el hormigón de control y el hormigón de la investigación. Los resultados revelaron buen comportamiento mecánico del hormigón que contiene proporciones del 5%, 10% y 15% de virutas de acero como agregado fino, sus resistencias superaron la nominal (240 kg/cm2) por lo que es considerable realizar investigaciones futuras con porcentajes superiores.   \u0000  \u0000Palabras clave — hormigón, virutas de acero, resistencia a la compresión, resistividad superficial. \u0000  \u0000Abstract ─ The use of materials from steel waste in turner’s workshops have a great importance in environmental and economic matters, because it reduces the amount of leftovers, favoring and prioritizing the care of the environment and the reducing of raw material in civil constructions. With the purpose of giving additional use to the steel shavings generated in the turner workshop, the city of Portoviejo has developing a research towards to partially replace the fine aggregate in the concrete with this material, in order to obtain integration alternatives in the constructive process and at the same time create sustainable development of the city. This research is based on the analysis of the mechanical performance of concrete through resistance compression tests as indicated by (NTE INEN 1573, 2010), and resistivity surface (AASHTO TP 95-11, 2011), using steel shavings as a fine aggregate in percentage substitutions of  5%, 10% and 15%.

Ecuador en su costa oriental del océano pacifico forma parte del llamado “Cinturón de Fuego del Pacifico” que se especifica por ser una de la zona del planeta que esta denominado como tal debido a que es la región más susceptible de experimentar los efectos de terremotos y erupciones volcánicas. Se lo caracteriza de tal manera ya que se puede apreciar muchos cambios en la superficie del planeta como respuestas a la interacción de las llamadas placas tectónicas. Para el caso del Ecuador, la interacción entre las Placas Sudamericanas y la Placa Nazca genera una zona de subducción frente a las costas y varias zonas tectónicamente que produce grandes sismos dentro al país. Los terremotos, son el resultado de la rotura de las rocas, liberando súbitamente energía en un punto determinado de la corteza terrestre.
