Avaliação qualitativa do uso tijolos de solocimento com incorporação dos resíduos de vidro produzidos no município de Itajubá/MG

Abstract

The use of soil-cement bricks in engineering works is considered an inexpensive and sustainable method compared to that used in conventional ways (ceramic or concrete blocks), considering that one of the raw materials used in this technique has wide availability, the manufacturing process is less harmful to the environment, in addition to its ease in the construction process. Combined with responsibility for resource management, time and environmental awareness, in Itajubá, south of Minas Gerais, there is a concern about the management of solid waste, especially glass waste, which exists in quantity in the region. In view of this, this research aims to evaluate the soil-cement bricks with the addition of glass residues, which were analyzed as to the feasibility of being incorporated into the composition of the soil-cement mixture, in order to use such residue productively, in order to be used as a new material. The granulometry tests, the Atterberg limits, density and specific mass were carried out with the soil used in the manufacture of the bricks, with the purpose of characterizing it and verifying its use in the soil-cement composition. In addition, the bricks made were subjected to tests of resistance to compression and water absorption, in which the bricks themselves were used as specimens, based on the recommendations of the ABNT NBR 8492 (2012) standard. The contributions of this research demonstrate that the insertion of glass waste in soil-cement bricks is beneficial, making technology productive and the need for viable solutions to minimize impacts on urban and rural areas, a way of optimizing the use of local resources in the implementation of future constructions using this technique.
