This paper assesses the effect of recycled date pits waste additive as a construction material additive to unfired clay bricks, with m Multiple waste additive proportions (0%, 1%, 3%, 7%, 15% and 20%), by weight, in terms of their physicochemical, mechanical and thermal performances. Crystalline characterization of used clay in its raw state, via X-ray Diffraction, showed its Illite type with non-swelling characteristics. While the chemical composition analysis, following X-ray Fluorescence, reflected the presence of several elements in Bensmim clay, such as Silica (SiO₂) and Aluminum oxide (Al₂O₃) making it a suitable construction material with a rich clayey structure. The incorporation of higher waste additive content in the bricks’ composition resulted in the production of more porous samples. In fact, specimens with 20% waste additive percentages, which is the highest evaluated proportion, reflected the highest recorded porosity level of 18.51%, compared to 1.17% of reference samples. This prompted in the production of brick samples with a lightweight structure, according to Moroccan testing standards NM EN 772-13 conformed to ASTM C20-00, and increased capillary water absorption coefficient of 49.75 g/(cm².min^0.5) in contrast to reference samples of 26.50 g/(cm².min^0.5). In addition, mechanical threshold analysis, produced brick samples of Earth Blocks Class 3 (EB3) and Earth Blocks Class 4 (EB4), that can be used non-load bearing and load bearing building structures, respectively. Waste additive-based samples of 20% waste additive proportion reflected samples of a 4.02 MPa and 0.98 MPa compressive and flexural strengths, respectively compared to 6.17 MPa and 4.65 MPa of reference samples. The incorporation of waste additives content in the bricks’ matrix reflected enhancements in the specimens’ thermal stability. In fact, recorded gains in thermal insulating properties were of 37% for thermal conductivity and 21% specific heat capacity compared to reference samples; as well as 68% and 47% energy savings in terms of thermal cooling and heating loads, respectively, following an energy simulation of a reference house.

本文评估了再生枣核废料添加剂作为未烧制粘土砖的建筑材料添加剂的效果，以重量计，多种废料添加剂比例（0％，1％，3％，7％，15％和20％）就其物理化学，机械和热性能而言。通过X射线衍射对原始状态下使用过的黏土进行结晶表征，表明其具有非膨胀特性的伊利石型。在进行X射线荧光分析后，化学成分分析反映出Bensmim粘土中存在多种元素，例如二氧化硅（SiO ₂）和氧化铝（Al ₂ O ₃）使其成为具有丰富黏土结构的合适建筑材料。在砖的成分中掺入较高的废物添加剂含量导致产生更多的多孔样品。实际上，废物添加剂百分比为20％（是最高评估比例）的样品反映出最高的记录孔隙度水平为18.51％，而参考样品为1.17％。根据摩洛哥测试标准NM EN 772-13（符合ASTM C20-00），这促使生产轻质结构的砖样品，与之相比，毛细管吸水系数增加了49.75 g /（cm ² .min ^0.5）。参考样品26.50 g /（cm ² .min ^0.5）。此外，通过机械阈值分析，生成了3级土块（EB3）和4级土块（EB4）的砖样品，可分别用于非承重和承重建筑结构。废物添加剂比例为20％的废物添加剂基样品分别反映了4.02 MPa和0.98 MPa的抗压强度和挠曲强度，而参考样品为6.17 MPa和4.65 MPa。砖基质中掺入的废添加剂含量反映了样品热稳定性的提高。实际上，与参考样品相比，记录的绝热性能的热导率增加了37％，比热容增加了21％。分别在热冷却和热负荷方面分别节省68％和47％的能源，
