Abstract:
The objective of this work was to add blands of a so-called combustible waste (jabuticaba bark) and a flux waste (packaging glass) in a ceramic mass, evaluating the properties of fired ceramics. The ceramic mass and the glass were characterized by XRF and XRD. The raw materials were dried and sieved so that formulations could be made with different percentages and mixtures of waste. Specimens measuring 114 X 25.0 X 11.0 mm were produced with a pressure of 10ton, and fired at temperature of 950°C. Afterwards, the following properties were evaluated: water absorption, linear shrinkage, and three-point flexural strength. With the results obtained, it was observed that because it is a waste with a large amount of organic matter, the jabuticaba peel alone would harm the properties of ceramics, and should only be used in small quantities. When blands were made with the two waste, even burning at lower temperatures, there was a significant improvement. With this, it is possible to conclude that the incorporation of the mixture of the two wastes in ceramics is a very advantageous alternative, both from the environmental point of view, for the disposal of these wastes, and for the ceramic industry, where in addition to improving the quality of the pieces, it has savings energy in the burning process
