摘要

The objective of this study is to experimentally determine the thermophysical properties (thermal conductivity and specific heat capacity) of a new, cost-effective, and environmentally friendly clay-based composite, incorporating argan shell powder as a partial substitute. Given the increasing importance of sustainable construction, integrating materials derived from waste and renewable natural resources into building materials represents an effective strategy for enhancing thermal performance while reducing environmental impact. To achieve this, several samples were prepared in the laboratory with varying proportions of argan shell powder, ranging from 5 to 30%, in 5% increments, to evaluate their thermal behavior. Microstructural and chemical analysis was performed using a scanning electron microscope coupled with energy-dispersive X-ray spectroscopy. The thermophysical properties (thermal conductivity and specific heat capacity) were measured in a dry state using a cylindrical probe CT meter at different temperatures (20, 30, 40, and 50 °C). At 20 °C, the substitution of 30% argan waste reduced the thermal conductivity, specific heat capacity, thermal effusivity, and thermal diffusivity by 56.5%, 15.3%, 40%, and 47.41%, respectively. Additionally, these thermal properties decreased with increasing temperature. These results highlight the potential of argan shell powder as an effective additive to improve the thermal insulation of clay bricks, offering a sustainable construction solution that optimizes the use of local resources while reducing energy consumption and production costs.
