The slurry collected from the waste water resulting ceramic tile processing contains significant amounts of quartz, kaolinite, and mullite, along with traces iron hydroxides as observed using XRD analysis coupled mineralogical optical microscopy (MOM). Such an admixture would be ideal for development ecologic building materials. Microstructural conditioning enhances binding properties kaolinite. Therefore, influence vibration compaction moistened at 30% humidity on compressive strength was assessed. unvibrated sample is about 0.8 MPa failure promoted by microstructural unevenness. Several amplitudes were tested 20 to 40 mm. optimal mode obtained amplitude 25 mm 10 min, ensuring a 2.37 smooth uniform surface involved within layer SEM microscopy. samples prepared under conditions thermally consolidated 700, 800, 900 °C below mullitization temperature ensure low carbon footprint. results reveal kaolinite dehydration in all fired samples, inducing its densification, which increases increasing heating temperature. EDS elemental investigations that dehydrated better embeds quartz mullite particles, compact microstructure. firing particles induce partial matrix, their homogeneity. compression dependent: 4.44 700 °C; 5.88 800 °C, 16.87 °C. fractography shows occurs due matrix cracks particles. rather plastic temperatures becomes brittle Reducing treatment time reduces footprint parts. Samples exhibit comparable quality bricks, those regular superior high-quality bricks.
