ABSTRACT
This study focuses on the valorization of peanut shell waste. The crushed peanut shells are used in this study to reinforce the composite construction materials based on local clay. Grain size tests and methylene blue tests were carried out on the soil studied to verify the recommended Craterre's limits. The results show that the soil satisfies these conditions for adobe construction. A series of 10×10×2.6 cm3 samples of this new composite was developed using different mass fractions of peanut shells. The thermal conductivity and diffusivity of studied samples were determined using the hot plate method and flash method, respectively. The obtained results show that the addition of 9% of the peanut shells can decrease the thermal conductivity and diffusivity of clay material from 0.623 W.m-1.K-1 to 0.323 W.m-1.K-1 and 4.8 m2.s-1 to 3.5 m2.s-1, respectively, which confers to this eco-friendly construction material the thermal insulation quality. In addition, a thermal dynamic simulation was performed on the thermal behavior of a traditional building located in the high Atlas Mountains in South Eastern Morocco demonstrating how traditional architecture and composite clay materials affect thermal comfort and building energy use in response to outside temperature and humidity variations.
