Abstract
El Hormigón ha sido útil para la sociedad desde hace más de 2000 años y es hoy en
día el material de construcción más utilizado en todo el mundo. Su uso es esencial
en nuestra sociedad moderna ya que proporciona una solución rentable, es duradero
y se adapta a casi todas las formas. Sin embargo su producción implica la emisión
de gases a la atmósfera generando un impacto ambiental.
La reducción del consumo de hormigón no debería ser la mejor alternativa a esta
problemática ambiental, ya que podría afectar seriamente el desarrollo económico
de una región o país, la solución está en el consumo sostenible. Una herramienta
que permite cuantificar y evaluar los impactos ambientales de un determinado
producto durante toda su vida útil es el Análisis del Ciclo de Vida (ACV).
Este trabajo tiene como objetivo brindar una primera aproximación al ACV de un
hormigón convencional localizado en Córdoba-Argentina; para ello se tuvieron en
cuenta los inventarios correspondientes a las materias primas y consumo de energía
involucrados en su elaboración. De este análisis surge que el mayor impacto se da
en la categoría de Calentamiento Global, siendo el dióxido de carbono (CO2) el que
presenta mayores cantidades, resultando ser menor su influencia en la acidificación
(disminución del pH del suelo y de las aguas) y eutrofización (proliferación de
plantas acuáticas que disminuyen la disponibilidad de oxígeno) del planeta.
ABSTRACT The concrete has been useful for the society for over 2000 years, and is today the most widely used construction material worldwide. Its use is essential in our modern society, providing a cost effective solution, durable and fits almost all forms. However its production involves the emission of gases into the atmosphere causing an environmental impact. Reduced consumption of concrete should not be the best alternative to this environmental problem as it could seriously affect the economic development of a region or country, the solution lies in sustainable consumption. A tool to quantify and assess the environmental impacts of a product throughout its life is the Life Cycle Assessment (LCA). This work aims to provide a first approach to LCA of a conventional concrete located in Cordoba, Argentina, for it took into account the inventories for raw materials and energy involved in its preparation. From this analysis it was observed that the greatest impact is in the category of Global Warming, being carbon dioxide (CO2) which presents greater quantities, proving less influence on acidification (decrease of soil pH and waters) and eutrophication (aquatic plants that reduce the availability of oxygen) of the planet.
