Abstract:
The construction sector consumes a large volume of raw material, in the case of ceramics, clay, an exhaust resource. In order to achieve sustainable growth, in view of the high demands of incorrectly disposed sediments, ornamental rock residues are used, extracted by the movement of diamond wire, in the cutting procedure of a rock block, as an alternative raw material. The objective of this Scientific Research is to prove the durability of these parts, in addition to acquiring burning temperature, percentage of residue, considering atmospheric agents. For this, three lots were divided (Intact, Natural degradation, Laboratory degradation), in all there are 14 pieces made in each percentage of aggregate residue (OR; 2.5R; 5R; 7.5R and 10R), which were burned at three temperatures (750ºC, 850ºC and 950ºC). The intact batch was submitted to moisture cycles with saline water, under accelerated condition in the laboratory. While natural degradation will be exposed to atmospheric conditions, o Laboratory degradation has the purpose of rapidly presenting the natural changes. The parts the that make up residue obtained a decrease in the variation of linear measurements, and less moisture for ceramic processes. Thus, the incorporation of waste, besides being sustainable, ensures greater resistance to the parts.
