Estudo da fabricação e caracterização estrutural de tijolos ecológicos a partir de materiais recicláveis visando aplicação em habitações sustentáveis

Abstract

The environmental impact problem of solid waste generated by consumption is the responsibility of every citizen. Respect for the law and protecting the environment is part of the environmental management process for the benefit of society and future generations. In this context, resolution should be sought alternatives and / or minimize this problem. This work aims to study the manufacture and structural characterization of ecological bricks of adobe type using as ultisol matrix and oxisol the Pontal do Paranapanema region and recyclable materials from the selective collection, construction and sugar industry (plaster, PET, EPS, vinasse) for potential application in sustainable housing. The methodology involved the study: physical characterization of the raw material (grain size, proctor-normal permeability test and chemical analysis of vinasse), the manufacturing process of ecological bricks and physical characterization (mechanical compression, water absorption, dry density, moisture content, behavior, stress / strain, acoustic behavior, temperature resistance, thermal analysis, electronic microscopy, mass comparison and compressive strength of the manufactured bricks) and recycling of green bricks (grain size and reuse). ecological bricks were obtained with different traits containing ultisol or oxisol, plaster, PET, EPS, vinasse and lime. Among the lines manufactured with ultisol only 2A trait and oxisol only 2L trait attended NBR 8492/12. The result of the physical characterization ecological bricks made in the above traits indicate that viability in the manufacture of green bricks with the proposed recyclable materials, and are potential for use in sustainable buildings.
