This work studies the reuse of spent shea waste as an economic construction material in improving fired clay bricks manufacture aside providing a novel approach to ecofriendly managing its excessive generated from the shea agroindustry. For this purpose, the influence of spent shea waste addition on the chemical, mineralogical, molecular bonding and technological properties (i.e. compressive strength and water absorption) of the fired clay bricks were extensively investigated. The results indicated that the chemical, mineralogical, phase transformations, molecular bonding and thermal behavior of the produced bricks were practically unaffected by the addition of spent shea waste. However, spent shea waste addition increased the compressive strengths and water absorptions of the brick products. Potential performance benefits of reusing spent shea waste was improved fluxing agents, energy-contribution reaction, excellent porosifying effect, reduced thermal conductivity and enhanced compressive strengths of the brick products. This research has therefore provided compelling evidence that could create newfound route for the synergistic ecofriendly reuse of spent shea waste to enhance clay brick construction aside being a potential mainstream disposal option.
这项工作研究了废牛油废物的再利用，将其作为一种经济建筑材料，用于改善烧制粘土砖的制造，同时为处理牛油农业产业产生的大量废牛油提供了一种新的环保方法。为此，广泛研究了废牛油废物的添加对烧制粘土砖的化学、矿物学、分子键合和技术性能（即抗压强度和吸水率）的影响。结果表明，废牛油废物的添加对生产砖的化学、矿物学、相变、分子键合和热行为几乎没有影响。然而，废牛油废物的添加增加了砖制品的抗压强度和吸水率。废牛油废物的再利用作为助熔剂、能量贡献反应、优异的成孔效果、降低导热系数和增强砖制品抗压强度，具有潜在的性能优势。因此，这项研究提供了有力的证据，为协同环保再利用废牛油废物开辟了新途径，除了作为一种潜在的主流处理选择外，还可以增强粘土砖的建筑用途。
