The aim of this study is to investigate the effects of incorporating fibers from the date palm tree into compressed earth blocks (CEB) in order to promote the utilization of local resources, reduce building costs, and minimizing energy consumption for temperature regulation. The primary objective is to examine how variations in compaction pressure and date palm fiber content influenced the mechanical properties of CEB when reinforced with these fibers. To achieve this, the study utilized four different fiber concentrations (0.1%, 0.3%, 0.5%, and 0.7% by weight of dry mix) and three lime contents (0%, 5%, 10%, and 12%). The researchers discovered that CEB produced with 0.5% fiber content and 12% lime exhibited improved dry and wet compression resistance as well as flexure resistance. However, when examining the other cases, the addition of fibers had an adverse impact on the properties of CEB.

Additionally, the study found a negative correlation between the fiber content and heat conductivity. As the proportion of fiber increased, the heat conductivity decreased. Consequently, incorporating lime and date palm fibers generally enhanced the mechanical and thermal characteristics of CEB.
