Resumen
En las últimas décadas la sociedad mundial ha incrementado su preocupación por la protección del medio ambiente, con el objetivo de alcanzar un desarrollo más sostenible. Sin embargo, existen sectores, como el de la construcción, que todavía son causa del elevado número de impactos ambientales, económicos y sociales; por lo tanto, requieren de una mejora en sus procesos. Para evaluar la sostenibilidad en el sector, es necesario reconocer, cuantificar y cualificar tanto los recursos como las emisiones en las diferentes etapas del proceso. Los aditivos son un componente importante del concreto, conjuntamente con el cemento, agua, agregados. En nuestro país, los aditivos que se utilizan son importados, lo cual implica altos costos para el país y gasto en divisas. La sustitución de productos importados por aditivos de producción nacional con características similares, de origen orgánico y medioambientalmente amigable con el medio ambiente posibilita la obtención de un hormigón más sostenible.En la presente investigación, se evalúa la sostenibilidad de la producción de hormigón a partir del uso de aditivo nacional MEF 32, lo que permite cuantificar el impacto de sustituir aditivos comerciales en la ECOT Cayo “Santa María” mediante un análisis de Ciclo de Vida, este puede resultar de gran utilidad para el proceso de planeación estratégica y la toma de decisiones para la entidad.
During the past decades world society has witnessed a growing concern about the protection of environment for sustainable development. However, sectors like construction still have a negative impact on the environment, which at the sometime bring about negative impacts on the economy and on society in general. That is why it crucial for the construction sector to improve its processes. In evaluating sustainability in the construction sector it is necessary to acknowledge, quantify and qualify resources and emissions along the process. Admixtures are an important component of concrete, together with cement, water and aggregates. In our country some these are imported when necessary, which implies, for our country, spending hard currency and paying high prices. Thus, producing organic and environmentally friendly admixtures locally, with identical characteristics to those imported is crucial for sustainability. This research is aimed at evaluating the sustainability of locally produced concrete using domestic admixtures MEF 32, which allows the quantification of the impact attained when substituting commercially available admixtures at ECOT Cayo Santa María, through a Life-Cycle Assessment, which may be useful for strategic planning and decision making in this organization (ECOT).
