Análise do desempenho térmico em tijolo ecológico confeccionado com uso de argila expandida

Abstract

Despite being one of the most representative field in the Brazilian GDP, the civil construction still has old construction thecniques that exarcebate the natural sources and use polluting materials. On the other hand, new sustainable materials that optimize the construction process are coming up. The soil-cement brick with expanded clay addition was created in order to get a final product that has good heat resistance characteristics. It is worth mentioning the environmental aspects for the production of this type of ecological brick that during its fabrication process no electricity is needed and no environmentally harmful gases are released. The parameters analyzed were the soil description, water absorption index, compressive strength and a practical test for heat transfer analysis. This test is a comparative method between four types of masonry that are ceramic block, concrete block, soil-cement brick and soil-cement brick with expanded clay addition. Then it is possible to detect which masonry has the best thermal comfort. Other results obtained through the tests with ecological bricks with expanded clay addition are promising related to compressive strength, thermal resistance and its final mass of ecological brick.
