Restoration materials from fibre waste have significantly developed over the past decade. In reality, the properties of this type of material offer numerous advantages, particularly in terms of thermal and acoustic insulation for old buildings being restored. Moreover, the ability of this material to incorporate the specifics of local architecture, especially in restoration projects, will undoubtedly invigorate the region’s landscapes. The main objective of this on-going work is to characterise this type of special material made from palm fibres/clay, which was recently developed at the LGEM laboratory of the University of Biskra. The palm wood used comes from the Biskra region, which produces the best dates in the world. The study focuses on morphological analysis and surface roughness using an optical microscope, a scanning electron microscope (SEM), and a non-contact three-dimensional measuring device. The chemical, physical, thermal, and acoustic properties were studied using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and an ultraviolet stabiliser, with the addition of a slip inhibitor and a blocking inhibitor as the main additives. Furthermore, this material has been subjected to antibacterial tests to prevent health issues. The results showed that using this material improves restoration buildings’ mechanical and energy performance.
