摘要
Production of ceramic bricks from mixtures of ceramic industry wasters and kalinitic clay were investigated. Different formulations were prepared to evaluate the effects of each component on drying and firing processes and on the final properties of the ceramic bricks. The samples were investigated mineralogically sing FTIR specra recorded in the region 4000-400 cm(-1) and powder X-ray diffraction. The indication of well ordered kaolinite is by the band at 1115 cm(-1) in the raw samples which tends to shift towards 1095 cm(-1) in all the fired samples. The presence of quartz and anorthite is confirmed both by XRD and FTIR. The samples were analyzed for their mechanical strength up to 50 wt % of the rejects additino before and after sintering (900-12000 degrees C). Additions above 40 % decreased the mechanical strength of both the dry body and the fire ceramic pieces.
