    Los desechos de ladrillos refractarios, sumado a los incendios que se originan en las estructuras, hacen posible juntar dos problemáticas para contribuir a una construcción sustentable para introducir nuevas alternativas de áridos en el concreto. El objetivo del estudio fue producir concreto con menos agregado fino y evaluar un concreto más sostenible, utilizando residuos de ladrillos refractarios (RLR) para reemplazar el agregado fino en cinco porcentajes 10 %, 20 %, 30 %, 40 % y 50 % para ser expuestos a fuego directo. El diseño se basó en una relación agua-cemento a/c de 0.71 y en la elaboración de 144 probetas de hormigón a base de RLR. Las muestras frescas se sometieron a ensayos de asentamiento y peso unitario fresco, las probetas cilíndricas preparadas tras 28 días de curado se sometieron a resistencia a compresión a temperatura ambiente y diversas temperaturas (200 hasta 1 000 °C) durante diferentes tiempos de 15, 30 y 60 minutos. Además, se realizó un análisis estadístico de varianza de Tres Factores con respecto a la resistencia a compresión a los 28 días. Los resultados mostraron que el RLR influye en que la mezcla de hormigón sea menos trabajable y reduzca el peso unitario fresco a mayores porcentajes de sustitución. Por otro lado, la dosificación ideal fue con el porcentaje de 40RLR a diferencia de las otras dosis sometidas a calor, siendo insignificante la exposición de 15 minutos, pero si relevantes a 30 y 60 minutos. Se concluye que el RLR influye significativamente en la mejora de sus propiedades mecánicas sometidas al calor elevado y la cantidad de residuos se limita a una dosis específica, lo cual proporciona un enfoque constructivo sostenible frente a exposiciones de fuego directo controlado.

    Refractory brick waste, added to the fires originated in structures, makes it possible to bring together two problems to contribute to sustainable construction and introduce new aggregate alternatives in concrete. The objective of the study was to produce concrete with less fine aggregate and to evaluate a more sustainable concrete, using refractory brick residues (RBR) to replace fine aggregate in five percentages 10 %, 20 %, 30 %, 40 % and 50 % to be exposed to direct fire. The design was based on a water-cement w/c ratio of 0.71 and the production of 144 RBR-based concrete specimens. The fresh samples were subjected to slump and fresh unit weight tests, the cylindrical specimens prepared after 28 days of curing were subjected to compressive strength at room temperature and various temperatures (200 to 1 000 °C) for different times of 15, 30 and 60 minutes. In addition, a Three Factor statistical analysis of variance was performed with respect to the compressive strength at 28 days. The results showed that the RBR influences the concrete mix are less workable and reduce the fresh unit weight at higher substitution percentages. On the other hand, the ideal dosage was with the percentage of 40RBR as opposed to the other dosages subjected to heat, being insignificant at 15-minute exposure, but relevant at 30 and 60 minutes. It is concluded that RBR significantly influences the improvement of its mechanical properties under high heat and the amount of residues is limited to a specific dosage, providing a sustainable constructive approach to direct controlled fire exposures.
