ANÁLISIS DE LA APLICACIÓN DE RESIDUOS DE CALIZA EN SISTEMAS CEMENTICIOS A PARTIR DE UNA REVISIÓN SISTEMÁTICA DE LA LITERATURA

Limestone is a sedimentary rock composed mainly of calcite and aragonite, both composed of CaCO₃, and may contain magnesium (dolomite). Its mining causes environmental problems due to the inadequate disposal of the waste generated. This study aims to identify the applicability of limestone residue from rocks in cementitious systems and to evaluate the techniques used to analyze these residues and their products. The method used was bibliographic research with Systematic Literature Review (SLR) as a tool. Limestone waste is generally calcitic and originates from quarries that extract carbonate rocks. Chemical and/or mineralogical analysis of the residue is not always performed, and there is no predominance of characterization regarding particle size, shape, and texture. Furthermore, most studies do not describe the state of the residue at the collection site and do not detail the preparation of the residue for use. Limestone waste has generally been applied in the form of a filler, partially replacing fine aggregate or cement in mortars. Its use in mortar production is viable and beneficial and can maximize new research on the use of waste, as well as help reduce the extraction of non-renewable natural resources.
