Resumen

Reutilizar subproductos para el desarrollo de bloques de hormigón que sean más sostenibles y con mejores propiedades térmicas, para el sector de la edificación es una necesidad y buena alternativa a desarrollar en el sector construcción. Se realizó un análisis del ciclo de vida (ACV) a los bloques con y sin subproductos, a fin de cuantificar los beneficios medioambientales que conllevaría la incorporación de estos subproductos en los bloques. El ACV se realizó de acuerdo con lo establecido en la norma EN-ISO 15804, que establece las reglas de cálculo para el análisis de productos de construcción. Este análisis se ha realizado mediante la herramienta de software “Eco-it”, con un alcance de la cuna a la puerta. Con base a los resultados se puede concluir que, la sustitución parcial del árido fino por las virutas y del cemento por los lodos de cal en la mezcla, es una vía alternativa para obtener bloques más respetuosos con el medio ambiente y a su vez con mejores propiedades térmicas.
