- Effect of use residual sludge from water treatment plants as a partial substitute for clay for refractory bricks production Alejandra Sarabia-Guarín Jorge Sánchez-Molina Juan Carlos Bermúdez-Carrillo Ingeniería residual sludge refractory bricks Pyroscopic resistance water treatment plants The sludge generated from water treatment has been classified as a potential environmental pollutant. Because of its chemical composition similar to clay, was proposed to evaluate the effect of its incorporation as a partial substitute for traditional clay materials in the manufacture of aluminosilicate refractory bricks. The raw materials used were characterized by XRD and XRF; the prototypes designed were mixed, extruded, dried and firing at 1200 °C, evaluating their linear shrinkage, apparent density, porosity, water absorption and mechanical and pyroscopic resistance (melting cone softening point). The results show the addition of 10% of sludges from industrial water treatment plant, contributed to elevate the softening point the clay that obtaining a refractory brick capable to supporting a temperature up to 1430 °C. 2021 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553768365002 https://www.redalyc.org/journal/5537/553768365002/ https://www.redalyc.org/journal/5537/553768365002/html/ https://www.redalyc.org/journal/5537/553768365002/553768365002.epub https://www.redalyc.org/journal/5537/553768365002/movil https://doi.org/10.18273/revuin.v20n1-2021002 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.1 Vol.20
