title = "Effect of use residual sludge from watertreatment plants as a partial substitute forclay for refractory bricks production",
abstract = "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.",
