摘要

The main objective of this work is to develop a new material based on palm fibers to enhance the thermal insulation of buildings. In this context, seasonal waste collected from palm trees can be used as a renewable insulating material to reduce energy consumption. This study investigates the potential of using palm fibers to improve the thermal and mechanical properties of insulation materials in Algeria. First, the palm fiber was prepared in block form with dimensions of 0.1 × 0.08 × 0.03 m3 by adding 5% of a starch-based natural adhesive to prevent undesirable chemical reactions. On the other hand, thermal and mechanical tests were conducted on a newly developed insulation and composite material based on reinforced concrete doped with palm fiber in percentages of 0.5%, 1%, and 1.5% with dimensions of 0.07 × 0.07 × 0.27 m3 used for flexural testing and 0.07 × 0.07 × 0.07 m3 used for compression testing. The results revealed that incorporating palm fiber into construction materials leads to a reduction in overall energy consumption. Moreover, the findings suggest that palm fiber-based composites could be a viable alternative to conventional insulation materials, offering enhanced performance and durability.
