Abstract
This study aims to assess the impact of incorporating argan nut shells into compressed earth blocks (CEB) with the objectives of leveraging local resources, minimizing construction expenses, and addressing housing shortages. To investigate the thermal behavior of compacted earth blocks reinforced with argan nut shells, considering multiple parameters such as aggregate quantity, size, and shape (powder/fibers), a range of samples were stabilized with varied proportions of argan nut shell powder and fibers, spanning from 5 to 30%. The thermal properties of the composite materials underwent experimental measurement using a thermal conductivity device (CT-meter) in dry conditions at a room temperature of 20 °C. The results indicated a substantial decline in thermo-physical properties in bricks with 30% argan powder incorporation compared to those stabilized with argan fibers. Notably, there was a significant reduction of 56.5% in thermal conductivity, 47.41% in thermal diffusivity, and 40% in thermal effusivity. These findings highlight the potential of integrating argan nut shells into CEB to enhance thermal insulation properties. This approach shows promise for sustainable construction practices, tap** into local resources and potentially reducing overall building costs.
