Avaliação das propriedades físico-mecânicas de revestimentos cerâmicos incorporados com resíduo de quartzito em pó.

Abstract

Civil construction is responsible for the transformation of the natural environment into a built place, due to this impact on the environment, economy and society, it is necessary to apply new knowledge to sustain the balance on the planet. The great abundance of resources left behind by buildings has worried several countries, due to environmental and sustainability issues. Analyzing the constant technological development and the needs of production methods in the area of ceramic coatings, this work sought to evaluate formulations of ceramic coatings incorporating quarzite powder residue to obtain ceramic coatings. The main purpose of this work is to study the influence of the quartzite powder as well as the physical and mechanical properties of the ceramic coating. For this, the characterization of the raw materials by X-ray fluorescence, X-ray diffraction, thermody- gravimetric and thermogravimetric analysis was done, and formulations (10% and 20% by weight powder quartzite residue) were made were burned at temperatures of 1000 ° C and 1200 ° C. After the firing, the specimens were submitted to tests to determine the physical-mechanical properties, among them: water absorption and flexural stress. It has been found that the results obtained a tend to the minimum limits required for the production of ceramic coatings.
