Resumen
El presente trabajo evalúa el uso de la adición combinada de caliza con arcilla calcinada obtenida a partir de la molturación de piezas de cerámica roja, en la producción a escala local de cemento de bajo carbono LC3, para su posterior utilización en la fabricación de bloques huecos de hormigón de 10 cm de ancho, así como elementos prefabricados, además de un hormigón de hasta 20MPa. El aglomerante fabricado presenta un 50% de cemento P-35 más la adición de un 30% de Arcilla Activa Térmicamente (AAT) y un 20 % de caliza. La fabricación del cemento se realizó en el Taller de Mantenimiento de Agabama, municipio Fomento, donde se usaron equipos de moliendas, de mezclado y una máquina bloquera de vibro-compactación propia del taller. Al cemento LC3 se le realizó el ensayo de finura mediante el método del tamizado, además de los ensayos de campo especificados en el Manual de Calidad de cemento de bajo carbono se evalúa en consecuencia, el índice actividad puzolánica, la finura, el fraguado y el carácter hidráulico de los mismo. Se obtienen además resultados a nivel de laboratorio para evaluar la idoneidad de los bloques huecos y de los hormigones de 20 MPa usualmente empleados en la producción local para la obtención de diferentes elementos de pequeño formato.
The current paper tests the combined adding of lime stone with calcined clay that is obtained from the grinding of red clay bricks when producing Lime Calcined Clay Cement (LC3) at a local scale. This cement is used for producing 10 cm hollowed concrete bricks, as well as pre-fabricated components and concrete up to 20MPa. This binding material obtained contains 50% of P-35 cement, the addition of 30% of thermally activated clay and 20% of limestone. The production of the cement was carried out at the Agabama maintenance workshop in Fomento municipality. To obtain the final outcome, there was used grinding and mixing machinery along with a block machine based on vibration and crushing. A Fineness test was also applied to this product using the sieve method and field trials on the area as indicated in the LC3Quality Book. This testing process takes into account the pozzolanic cement activity indicator, the fineness, the setting, and the hydraulic character of the cement. Moreover, Lab results were also obtained in order to calculate the appropriateness of the 20MPa concrete hollowed blocks commonly used for the local production to obtain different minor scale components.
