“…The diffraction peaks observed in the C1-S 10% sample were more prominent than those in the other samples. This might be related to an increase in the temperature of the system owing to the high content of organics and higher humidity of the mixture [51,52]. The diffractograms of the samples produced with C2 showed peaks of quartz and hematite because kaolinite and mica were consumed with increasing temperature (480 °C and 850-940 °C, respectively).…”

This study evaluated the grain size and high organic content from drinking water treatment sludge (DWTS) in the properties of ceramics. Samples were studied using raw and oven dried DWTS at 110 °C in two granulometries (0.180 mm and 0.075 mm), with and without calcination (550 °C), as partial replacement of two soils commonly used in ceramic production. Specimens were prepared with 5, 10, and 20% DWTS and calcined at 950 °C to determine their chemical, physical, mineralogical and mechanical properties. The DWTS reduced the density and increased the absorption and shrinkage of the specimens after calcination. An increase in strength with up to 10% sludge, driven by the presence of fluxing agents, was verified. The processing method had little influence on the properties of ceramic with above 10% of sludge. In conclusion, the use of raw DWTS obtained better results with low energy usage for its reuse.
