Características e propriedades de produtos obtidos de formulações entre o resíduo da cerâmica vermelha, resíduo de gesso e resíduo do poliestireno

Abstract

With the growing population and use of non-renewable resources by current and future generations, there is also growing concern about the environmental impacts caused by man and his creations. Currently PS or polystyrene has features of easy molding, low cost, high strength. The properties of red ceramic and plaster allow them to be applied on a large scale. The execution of this work followed the following steps: obtaining, preparation, characterization and formulations among the residues; determination of the properties of the materials obtained and mechanical testing. Where the formulations were prepared by adding three different concentrations of red ceramic residue, plaster residue and PS: A (1: 1 Ceramics / PS), B (1: 1: 2 Ceramics / Gypsum / PS) residues and C (1: 1 Gypsum / PS). The objective of this work was to study the formulations between the red ceramic residue, the plaster residue and the PS residue, in order to analyze the physical and mechanical properties. The results indicate that the addition of PS residue to red ceramic residue and to plaster residue influence differently on and properties. The specimens presented mechanical flexural strength values of 1420.87 MPa, 1112.26 Mpa and 890.78 Mpa for formulations A B and C respectively. Tests for the determination of technological properties such as bulk density, apparent porosity and water absorption showed that the specimens containing red ceramic and PS showed more effective results.
