Moisture sorption characteristics of Compressed Earth Bricks stabilized with cement and reinforced with bentonite clay

This study investigates the hygroscopic properties of Compressed Earth Bricks (CEB) stabilized with varying amounts of bentonite and cement, ranging from 0 % to 8 %. The primary aim is to assess how these stabilizers influence moisture retention and regulation under different temperature conditions. Experimental analyses were conducted at 30 °C, 40 °C, and 50 °C, with relative humidity levels spanning from 5 % to 90 %. The findings indicate that cement incorporation decreases moisture absorption and enhances the bricks' resistance to climatic fluctuations. However, at elevated humidity levels, structural imperfections emerged, likely due to modifications in the material's pore network. To further understand these moisture interactions, analytical methods were employed, offering valuable insights into the material's response to diverse environmental conditions. These results contribute to optimizing CEB formulations for improved durability and adaptability in sustainable construction across various climates.
