Abstract
Wastes generated by processing ornamental stones are an increasing environmental problem in Brazil. Recycling alternatives are being investigated for the different types of wastes. The addition into clay ceramic is a possibility as long as the stone waste presents compatible characteristics. Therefore the objective of this work was to characterize a waste obtained from the sawing operation of granite by a steel multi-wire equipment as well as to evaluate its effect on the plasticity of clayey formulations. This characterization was performed in terms of chemical composition, X-ray diffraction and particle size distribution. The results indicated not only similar chemical and physical aspects but also a potential for addition into clay bodies of Campos dos Goytacazes in the state of Rio de Janeiro, Brazil, by the adjustment of the excessive plasticity of the clay.
