DESEMPENHO TÉRMICO DE TIJOLOS ECOLÓGICOS EXPERIMENTAL COM EPS E AGREGADOS MINERAIS: ANÁLISE POR INFRAVERMELHO

The growing concern about the environmental impact of the construction industry has driven the development of sustainable materials with improved energy performance. In this context, this study aims to evaluate the thermal performance of eco-friendly bricks produced with CP II-F 32 Portland cement, mineral aggregates (sand and phyllite), and shredded expanded polystyrene (EPS). Phyllite was used as a partial replacement for fine aggregate due to its pozzolanic potential and low cost, while EPS contributed to reducing the density and enhancing the thermal insulation capacity of the bricks. The bricks were molded in wooden forms with standardized dimensions (12.5 x 25 x 7 cm), including two vertical holes according to NBR 10834:2013. After curing for 14 and 28 days under controlled conditions, the specimens were subjected to thermal tests based on heat conduction, using halogen lamp radiation and temperature measurement via infrared thermometer. The temperature variation on the opposite face of the heat source allowed for comparison between the different mixes. The expected results should demonstrate that the incorporation of EPS and phyllite directly influences the thermal insulation capacity of the eco-bricks, validating their viability as a sustainable construction alternative.
