| Popis: | The building materials used in Morocco characterized by a low thermal resistance which generates a huge expense in terms of energy consumption. Promoting new sustainable construction and insulation materials become a necessity. This research study aimed to develop the thermal proprieties of plaster building material by mixing it with waste chicken feathers (WCF) in order to be used as wall exterior rendering. For the purpose of determining the thermal properties of the biocomposite material Plaster-WCF, several experimental measurements of thermophysical proprieties had been performed in order to determine apparent density, thermal conductivity, and thermal diffusivity using the hot plate method in steady-state regime and the Flash method, respectively. The results showed that the addition of waste chicken feathers leads to a remarkable reduction in apparent density of about 12.3%, the thermal conductivity and diffusivity have been reduced by about 30.2% and 18%, respectively, which shows the interest of using this biocomposite material in the construction buildings in order to ensure thermal comfort and reduce greenhouse gas emissions (CO2). |
