Characterization of a Bio-Composite material (Natural Hydraulic Lime/Date Palm Leaflet) for architectural restoration

This scientific investigation aims to characterize the physical and mechanical properties of a new biomaterial designed for architectural restoration. The biomaterial studied is a composite of natural hydraulic lime (NHL) and date palm fibre. The study reports the first experimental characterization of these restorative materials. A series of mortar compositions were prepared with different particle size (0.5, 1, and 1.5 mm). The results showed that the mortars containing DPL exhibited significant changes in their properties due to variations in particle size. Increased DPLP led to lower density but whereas mechanical strength. This research provides valuable insights into the use of sustainable and renewable building materials, highlighting the benefits of exploiting agricultural waste in the constructional sector. The findings lay the groundwork for future research and innovation in environmentally friendly construction technologies.
