Abstract
This article presents the morphological, chemical, and mineralogical characterization of the aggregates and concrete mixtures produced with simultaneous replacements of gravel by electric arc furnace slag, and sand by recycled ground glass. The gravel was replaced in percentages of 25%, 50%, 75% and 100% by slag. The sand was replaced by recycled glass in percentages of 20%, 30% and 40%. Slag was chemically and mineralogically characterized and its basicity determined. Recycled glass was characterized by a chemical microanalysis. For the chemical and mineralogical characterization of the materials, X-ray diffraction and X-ray fluorescence techniques were used. Concrete mixtures were structurally and morphologically characterized by scanning electron microscope analysis. The morphological, chemical, and mineralogical characteristics of the aggregates influence the morphological, chemical, and mineralogical characteristics of concrete mixture produced by them.
