Análise comparativa entre tijolos cerâmicos e tijolos de solo - cimento

Abstract

With the developments of constructive processes and the emergence of new materials, it is considered essential to the need to preserve the environment, already that, every day, there is an increase in the shortage of natural resources. New ideas and processes, aiming at sustainability are emerging , so reducing the environmental impacts . Unfortunately, the construction industry has been characterized as one of the main polluters and causing those impacts. There is thus a need for concrete that attitudes are taken, being made in this way the correct choice and conscious of the materials of construction. For both, it is necessary to identify, among the many materials available, those that cause minor impacts to the environment, by means of its production, use and final disposal. Having Made these observations, it can be highlighted the fact that the soil is a suitable material for the most diverse applications constructive, due to its abundance, ease of handling and obtaining and in addition to the low cost. As a result the ceramic brick is one of the most widely used products in the domestic market. The same is the result of the firing process of the clayey soil, modified, first, in molds, thus providing various forms. However, along with the new ideas that aimed at sustainability, is coming on the market of civil construction the bricks of soil-cement, which do not require the burning process and thus do not cause deforestation and CO2 emissions. But, with everything, note the small number of publications comparative between the two types of bricks. Thus, this study aimed to compare the ceramic bricks and the soil-cement, both massive, analyzing the same under environmental point of view and also constructive. For this purpose, were first carried out visits to a local pottery and a brick factory soil-cement and in sequence were performed tests such as: measurements of bricks, tests for resistance to compression and absorption index of bricks. With the analysis of the results, you can generate a comparison of manufacturing processes, concluding and demonstrating that the ground-cement bricks are more environmentally friendly. But i noticed that they are a little more expensive than the bricks of the pottery. Under constructive point of view, the two types of bricks obtained good resistance and good absorption. The choice of brick ends up being really based on product availability and cost, and often not on purpose.
