Research highlights A bio-sourced lightweight material based on raw earth and date palm waste aggregates is investigated. The thermal insulation performance of bricks incorporating date palm waste is significantly improved. The presence of date palm waste in the material has a significant impact on its mechanical performance. Date palm waste-based bricks are classified as weakly capillary, according to Standard NF XP 13-901.
Abstract Low cost building materials, thermal comfort, energy consumption reduction and lower carbon dioxide emissions are the main reasons for the renewed interest in the exploitation of local materials, in particular earth material and plant waste, in several countries throughout the world. In this context, the main purpose of the present work is to test a bio-sourced composite material, in the form of raw earth bricks, stabilized with lime and mixed with date palm waste (DPW) aggregates. This is done for the purpose of studying the effect of this waste at different contents (0, 2, 4, 6, 8 and 10% by weight) on the physical and thermal properties of the bricks obtained, and on their mechanical behavior. The results obtained revealed an improvement in the thermal insulation, with a thermal conductivity that went from 0.677 W/m.K, for test pieces with no date palm waste (DPW), to 0.342 W/m.K for those containing 10% of DPW. This improvement was accompanied by a reasonable decrease in the mechanical performance, while keeping the minimum performance threshold required by earthen construction standards.
