Characterization of a Granite Waste for Clay Ceramic Addition

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.
