The use of recycled fine aggregate from construction and demolition waste as a replacement for natural fine aggregate in the manufacture of masonry mortar represents an environmental benefit that must be quantified. The life cycle assessment is a procedure that allows to know the environmental impacts associated with a product throughout its life cycle; for that purpose, it incorporates a series of phases of which inventory analysis is one of the most important as it directly influences its overall quality. The main aim of this study has been to develop the life cycle inventory of masonry mortars made of natural fine aggregate and recycled fine aggregate in accordance with ISO 14040 and ISO 14044, and being the system subject of study from cradle to gate level, thus boundaries included the production of the mortar components (natural fine aggregate, recycled fine aggregate, filler, cement and additive) and the …
