Resumen
[es] Estudio de la retención de elementos contaminantes procedentes de residuos mineros en materiales cerámicos para la producción de ladrillos.
Estos residuos se han depositado durante décadas a la intemperie, provocando un grave problema de contaminación.
Para paliar estos efectos, se procede a la caracterización del residuo minero y obtención de su composición química. Posteriormente, se fabrican materiales cerámicos con distintos porcentajes de residuo minero valorizando estos y reduciendo el consumo de materias primas.
Se estudiará el comportamiento de la adición de estos en matriz cerámica, a partir de sus propiedades físicas y mecánicas después del proceso de conformación, así como, análisis de lixiviados para cuantificar la retención de los elementos contaminantes en el residuo.
Finalmente, se determinará el porcentaje máximo de residuo minero que se incorporará en el material cerámico para obtener unas propiedades aceptables según la normativa vigente.
[en] Study of the retention of polluting elements from mining waste in ceramic materials for the production of bricks. These wastes have been deposited in the open for decades, causing a serious pollution problem. To alleviate these effects, the mining waste is characterized and its chemical composition obtained. Subsequently, ceramic materials with different percentages of mining waste are manufactured, valuing these and reducing the consumption of raw materials. The behavior of the addition of these in ceramic matrix will be studied, based on their physical and mechanical properties after the shaping process, as well as leachate analysis to quantify the retention of polluting elements in the residue. Finally, the maximum percentage of mining residue that will be incorporated into the ceramic material to obtain acceptable properties according to current regulations will be determined.
