This study aims to carry out a Systematic Literature Review (SLR) on the assessment of environmental impacts resulting from the use of Supplementary Cement Materials (SCM) and Recycled Aggregate (RA) in construction materials, through the methodology of Evaluation of the Life Cycle (LCA). The methodology consisted of searching for scientific documents on LCA for the evaluation of concretes and mortars that use SCM and RA, in the Scopus and Web of Science databases, from 2015 to 2021. The results show that studies adopt a border of the cradle system to the gate, claiming that it is the most representative. To perform the LCA, secondary data are used, mainly databases (Ecoinvent and ELCD). Global Warming Potential is the common impact category, followed by Abiotic Depletion Potential and Acidification Potential. The methods used quantify only the intermediate effects of the impact categories; this step is preferably assisted by Simapro and OpenLCA programs. Studies have shown that the use of MCS and AR can reduce the environmental impacts of the evaluated concretes and mortars, but the reduction is greater when both are used at the same time than when used separately. ; Este estudio tiene como objetivo realizar una Revisión Sistemática de la Literatura (RSL) sobre la evaluación de impactos ambientales derivados del uso de Materiales Suplementarios de Cemento (MSC) y Agregado Reciclado (AR) en materiales de construcción, a través de la metodología de Evaluación del Ciclo de Vida (ECV). La metodología consistió en la búsqueda de documentos científicos sobre ECV para la evaluación de hormigones y morteros que utilizan MSC y AR, en las bases de datos Scopus y Web of Science, de 2015 a 2021. Los resultados muestran que los estudios adoptan una frontera del sistema cuna para la puerta, indicándose que es la más representativa. Para realizar la ECV se utilizan datos secundarios, principalmente bases de datos (Ecoinvent y ELCD). El Potencial de Calentamiento Global es la categoría de impacto común, seguida por el ...
