“…En la literatura científica se reportan pocos estudios sobre caracterización de EC antiguas (Ros-Latienda y Fernández-Carrasquilla, 2013) y del uso de EC de vertederos antiguos como un material conglomerante (Nazer et al, 2016). Otros estudios determinaron las propiedades cementantes de las EC en la fabricación de morteros (Ariño y Mobasher, 1999;Tixier et al, 1997;Taha et al, 2007;Sánchez de Rojas et al, 2008;Nazer et al, 2013) y hormigones (Al-Jabri et al, 2011;Thomas and Gupta, 2013;Mithun and Narasimhan, 2016).…”

RESUMEN:El objetivo de este trabajo es caracterizar 4 escorias de fundiciones de cobre del siglo XIX, procedentes de vertederos abandonados en la Región de Atacama -Chile, utilizando las técnicas de fluorescencia de rayos X (FRX), difracción de rayos X (DRX), microscopía electrónica de barrido (SEM), análisis de partículas por difracción láser (ADL), espectrometría infrarroja por transformadas de Fourier (FTIR) y análisis termogravimétrico (ATG). Las escorias de cobre estudiadas fueron clasificadas químicamente como escorias ácidas, con mayor contenido de SiO 2 (38 -49%) que de Fe 2 O 3 (18 -37%), y con una importante cantidad de CaO (8-26%) y Al 2 O 3 (5-8%). Su mineralogía y estructura es variada, presentando una de ellas una estructura amorfa y las tres restantes, una estructura cristalina con cierto carácter amorfo. Las fases minerales mayoritarias presentes en las escorias de cobre son diópsido, fayalita, magnetita, cristobalita y clinoferrosilita. Los niveles de calcio indicarían que las escorias poseen propiedades cementantes para ser utilizadas en materiales de construcción. Además, la importante cantidad de escoria disponible y el contenido de CuO (0,6 -1,2%) muestran que puede ser de interés como materia prima en la recuperación del metal. ABSTRACT: Characterization of chilean copper slag smelting nineteenth century. The aim of this work is to characterize four copper smelters slag nineteenth century, from abandoned landfills in Atacama Region -Chile, using the techniques of X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), particle analysis by laser diffraction (ADL), Fourier Transform Infrared Spectroscopy (FTIR) and thermogravimetric analysis (TGA). Copper slags studied were chemically classified as acidic slags, this slags presented higher SiO 2 content (38-49%) than Fe 2 O 3 (18-37%) and a significant amount of CaO (8-26%) and Al 2 O 3 (8.5%). Mineralogy and structure was varied, presenting one of them an amorphous structure and the remaining three, a crystalline structure with partially amorphous character. The majority mineral phases presented in the copper slag were diopside, fayalite, magnetite, cristobalite and clinoferrosilita. Calcium levels indicate that the slags could have cementitious properties for use as a binder in construction materials. Moreover, the significant amount of slag available and CuO content (0.6-1.2%) show that may be of interest as raw material for metal recovery.

“…77, for tensile and flexural strength respectively, are considered to be encouraging in that they suggest that CS can be accepted for use as sand in concrete and that Eurocode 2 can be used, in a normal manner, without any modification for estimating the tensile and flexural strengths of such concrete mixes. It should be noted that the results of Meenakashi and Ilangovan (2011) and Sudarvizhi and Ilangovan (2012) for ferrous slag and those of Nazer et al (2013) for mortar were excluded from the relationship for tensile strength and flexural strength, respectively.…”

This paper provides the gist of the systematic review undertaken, involving evaluation, analysis, repackaging and modelling of all the literature that could be sourced on the subject. Copper slag (CS) and washed copper slag (WCS), as to be expected, have essentially similar basic physical (although WCS is usually finer than CS) and chemical characteristics and therefore they can be treated as one material. In-depth analysis of 2192 test data sourced from the literature showed that, given all the basic material characteristics, CS/WCS can be used as the sand component for making all strength grades of concrete and giving similar (or in some aspects better) performance to the corresponding concrete made with natural sand. The special attribute of CS/WCS for lowering the mix water demand has been used by the authors to develop two simple models for utilising the potential water savings and estimating the strength gains that can be realised when designing concrete with CS/WCS for given strength at a specific age. It is demonstrated that the water-saving potential of CS/WCS can be used to make other recycled and secondary materials more acceptable for use in concrete.
