dc.description.abstract | In order to develop construction materials with greater efficiency and performance than conventional materials, mixtures of lightweight concrete (LWC) made from thermally expanded clay (TEC) have been generated. In this article we study the mechanical properties (equilibrium density, compressive strength) of the LWC mixtures produced with raw material from the metropolitan area of Cúcuta, contrasting their characteristics with conventional concrete (CC) mixtures. For this, the lightweight aggregates were developed by calcining clay pellets in a rotary kiln at a pilot plant scale at a temperature of 1050 ° C, generating an expansion of 1.60 times of its initial size. Following the methodology ACI 211.2-98 two concrete mixtures were designed: the first, with fine and coarse aggregate of TEC; and the second, with coarse aggregate of TEC and fine aggregate of sand. It was determined that the LWC mixture with the highest efficiency is the one that uses fine and coarse aggregate of TEC, since the density of the LWC decreased by 25% with respect to the density of the CC, maintaining the resistance to compression after 28 days Under the same conditions. In conclusion, LWC mixtures made from TEC with raw materials from the metropolitan area of Cúcuta have a lower equilibrium density and compressive strength similar to that of CC. | eng |

En el presente artículo se estudian las propiedades mecánicas (densidad de equilibrio, resistencia a la compresión) de las mezclas de LWC producidas con materia prima del área metropolitana de Cúcuta contrastando sus características con mezclas de concreto convencional (CC). Para lo anterior, se desarrollaron los agregados livianos calcinando pellets de arcilla en un horno rotatorio a escala de planta piloto a una temperatura de 1050°C, generando una expansión de 1.60 veces de su tamaño inicial. Siguiendo la metodología ACI 211.2-98 se diseñaron dos mezclas de concreto: la primera, con agregado fino y grueso de TEC; y la segunda, con agregado grueso de TEC y agregado fino de arena. Se determinó que la mezcla de LWC con mayor eficiencia es la que utiliza agregado fino y grueso de TEC, ya que la densidad del LWC disminuyó en un 25% con respecto a la densidad del CC, manteniendo la resistencia a la compresión a los 28 días en las mismas condiciones. En conclusión, las mezclas de LWC elaborados a partir de TEC con materias primas del área metropolitana de Cúcuta presentan una menor densidad de equilibrio y resistencia a la compresión similares a la de los CC. | spa |
