| description | The results of the characterization of ‘Flying Ashes’, FA, a product of coal burning are shown in this paper. The ‘flying ashes’ samples were produced in the thermal station Termopaipa IV, in the State of Boyacá, Colombia. The techniques used for the characterization were: X-Ray Fluorescence, X-ray diffraction, Optical Microscopy (Polished Thin Section) and Electronic Microscopy. It is noticeable that the ashes are made up of aluminum and silicon compounds. Besides, iron phases in low content such as hematite and limonite were also found. Additionally, the morphology reveals presence of coke unburned coal and spheres of different size and composition. According to the features found in this study, such as: chemical and mineralogical composition, and surface characteristics have determined that the FA is an artificial pozzolanic material with acidic properties, which influences the reactivity of the ashes that is based on the chemical aspect of the lime fixing and fulfil the requirements in a high degree according to the standard for use in the cement industry. |

En este trabajo se presentan los resultados de la caracterización de Cenizas Volantes, CV, producto de la combustión del carbón, las cuales fueron producidas en la estación termoeléctrica Termopaipa IV, de la región de Boyacá, Colombia. Las técnicas empleadas para la caracterización fueron: Fluorescencia de Rayos X , Difracción de Rayos X, Microscopía Óptica (Sección Delgada Pulida), Microscopía Electrónica de Barrido y Espectroscopía de Fotoelectrones de rayos X. Se observa que las cenizas presentan principalmente contenido de compuestos de aluminio y silicio, además, fases de hierro en menor escala como son Hematita y Limonita. La morfología revela inquemados de carbón y esferas de diferente tamaño y composición. A partir de las características encontradas en este estudio como son: composición química, mineralogía y características superficiales, se determina que las CV son un material puzolánico artificial con carácter ácido lo cual influye sobre la reactividad de las cenizas que se basa en el aspecto químico de la fijación de la cal y cumplen con los requerimientos para su utilización en la industria cementera.
