“…13d )], which were identified through the PDF-2 diffraction profiles database, thus, obtaining characteristic clays of the Norte de Santander raw materials for both Companies, and another region such as been reported by [12,32]. Also, is evident that the raw materials of Cucuta Company have minor impurities than Ocaña Company [7,33]. In this way, clay aid to obtain an adequate plasticity index, the Al 2 O 3 contributes to the flux, and the SiO 2 as a stabilizer [34].…”

“…The chemical and mineralogical compositions (Characterization of the raw materials) are one of the most important tests to evaluate clay and its influence during the ceramic process [1,7,8]. Plasticity (Physical characterization) is another critical parameter to control, understood as the property that clays have of forming a plastic and homogenous ceramic paste.…”

This work presents the physical-mechanical properties of two types of H-10 blocks of six holes fabricated in two different companies in Norte de Santander, Colombia to provide a general visualization of the ceramic properties of masonry products base clay. Random samples of H-10 blocks were collected from the selected companies directly from the furnace as part of the experimental procedure, which was used to perform the physical-mechanical tests such as initial and final water absorption, morphology, resistance to compression, and flexion according to the NTC 4017 standard procedure, the results obtained were compared with the values established in the NTC 4205 standard procedure, used as non-structural masonry products for indoor or outdoor use. Finally, the SEM-EDS micrographs exposed the maincharacteristic chemical elements (Al, Si, O), defects on the surface of an H-10 block and the presence of typical phases (Quartz, Kaolinite, Illite, and Hematite) obtained by the XRD technique.

“…Teniendo en cuenta la Tabla 3, se puede observar que la mejor formulación está en la mezcla 7 debido a que se acerca al porcentaje estimado como el óptimo con las características de las arcillas de la empresa, como también mantiene un equilibrio entre las materias primas, es decir que no se agoten las vetas de arcilla donde se recolectaron las muestras para los estudios. Además, las mezclas 3 y 9 podrían ser buenas formulaciones pero agotarían los recursos en cuanto a materia prima de una veta de arcilla rápidamente, teniendo en cuenta que la veta de arcilla de las muestras seleccionadas se encuentran en pequeña proporción en relación a las demás según el muestreo realizado en los patios de la empresa seleccionada para la investigación, caso contrario ocurre con la mezcla 9 pero se encuentra sobre la línea de la región formulada como óptima (58,5% Arena -20,1% Limo -21,4%) [28].…”

En la presente investigación se llevó a cabo la ejecución del ensayo de hidrometría a cinco muestras de arcilla de diferentes tipos de una de las empresas dedicadas a la fabricación de bloques H-10 en la región nortesantandereana con los que se determinaron los porcentajes de arenas, limos y arcillas; los cuales fueron ubicados en el diagrama de Winkler para identificar los tipos de arcillas existentes según su textura y el tipo de producto que se puede fabricar para poder formular una mezcla experimental de material cerámico utilizando el software Statgraphics Centurion XV. Los resultados obtenidos demuestran que las arcillas utilizadas actualmente por la empresa se encuentran en los índices mínimos para la elaboración de bloques H-10 con granulometrías superiores a 2 milímetros de diámetro. Con esta investigación se espera poder pronosticar el comportamiento de las mezcla en las etapas del procesos producto con la condiciones tecnológicas de empresa, con lo que evidentemente se mejoraran los recursos ambientales y económicos de la empresa.

The present research consists in the application of statistical tools for the monitoring of the energy efficiency of indicators in productive processes that comply with the requirements of ISO 50001:2011. This paper presents the methodology and the results in terms of forecasting (SGE) for the consumption of electric energy in the manufacture of H-10 blocks using the STATGRAPHICS Centurion XV Software. The outcomes demonstrated the stabilization of the energy efficiency associated with an increase of production without investment by purchasing new equipment. That is to say, that only with the innovation and the follow-up of the process through applied management technologies the resources of the company can beoptimized, besides the adoption of a culture of energy management in an efficient way. The energy efficiency is optimized taking into account all the variables that influence the production process, besides performing preventive maintenance of the equipment in order to stabilize and control theparameters involved in the manufacture of masonry products for construction.
