The aim of this work was to evaluate the waste (sludge) from waterworks of the Campos dos Goytacazes-RJ region. With this in view, the mineralogical and physical-chemical characteristics of the waste materials were studied for their use as raw materials in the red ceramic industry. As part of the study, a series of characterization tests, such as chemical analysis, X-ray diffraction, thermal analysis, morphological analysis, particle size analysis, cation exchange capacity and plasticity were carried out. The results indicate clearly that the ETA waste has potential to be used as raw material for the manufacture of red ceramics.
