Abstract:
With the great advances in the industry, the generation of waste from different sectors is increasing. Therefore, a measure is needed to mitigate the environmental impacts generated by the incorrect disposal of these wastes. In this sense, new techniques have been studied for their use, through the incorporation allowed by ceramic masses. By adding controlled amounts, it is possible to obtain a final product that provides the properties required in its applications, this can be acquired due to the natural variability of clays. Dyeing plants generate, during their washing and dyeing processes, effluents that can be discarded in nature and a solid sludge that must be treated due to the presence of heavy metals from dyes and dyeing aids. The objective of this work is to evaluate the potential of the incorporation of dyeing sludge in red ceramics. After the characterization of the raw materials, specimens were made by varying the percentage by weight of the sludge. Burned at 850°C, they were exposed to different tests to determine their properties, such as linear shrinkage, water absorption and flexural breaking strength. It can be seen the need to control the sludge content in the compositions, however, once applied, it is possible to successfully obtain the properties required for ceramic products. Thus showing the effectiveness of the incorporation of the residue in question in the preservation of the environment
