Wood sawdust, a byproduct of the wood industry, presents significant environmental and economic challenges due to its disposal. This study investigates the effects of incorporating wood sawdust into fired clay bricks on their physical and thermal properties. Five different clay and wood sawdust mixtures, labeled S1, S2, S3, S4, and S5, were prepared with sawdust proportions of 0%, 2%, 4%, 6%, and 8%, respectively. Both the clay and wood sawdust were subjected to comprehensive physical and chemical testing. Three samples from each mix were analyzed for bulk density, porosity, and thermal properties. The results show that the inclusion of wood sawdust significantly impacted the physical, and thermal properties of the bricks. As the sawdust proportion increased, the bulk density of the bricks decreased, while porosity increased. Moreover, the thermal properties of the bricks were notably enhanced with the addition of wood sawdust, indicating its potential to improve the thermal insulation performance of fired clay bricks. These findings suggest that incorporating wood sawdust into clay bricks could offer a sustainable solution to both enhancing their thermal efficiency and addressing waste disposal challenges.
木屑是木材工业的副产品，由于其处置问题，带来了重大的环境和经济挑战。本研究调查了将木屑掺入烧制粘土砖中对其物理和热性能的影响。制备了五种不同的粘土和木屑混合物，分别标记为S1、S2、S3、S4和S5，木屑比例分别为0%、2%、4%、6%和8%。对粘土和木屑都进行了全面的物理和化学测试。对每种混合物的三个样品进行了堆积密度、孔隙率和热性能分析。结果表明，掺入木屑对砖的物理和热性能有显著影响。随着木屑比例的增加，砖的堆积密度降低，孔隙率增加。此外，添加木屑后砖的热性能显著提高，表明其具有改善烧制粘土砖隔热性能的潜力。这些发现表明，将木屑掺入粘土砖中可以为提高其热效率和解决废物处置挑战提供一种可持续的解决方案。
