筛下残渣是地震和海啸产生的一种灾难废物，含有大量的木屑。这些残渣不能用作地面材料，主要是因为它的承载能力不足，而且对木片的腐烂过程还没有很好的了解。在这项研究中，使用两种与筛下残渣非常相似的木屑(纤维椰子木屑和颗粒状木屑)与矿渣和Iwaki砂进行了无侧限压缩(UC)试验。试验结果表明，掺量为10%的钴渣或海诺基矿渣的抗压强度高于单独掺入的矿渣。此外，对于体积比小于20%的椰子砂，与椰子砂混合的Iwaki砂的UC强度和变形模量都高于单独使用的Iwaki砂。
Under-sieve residue, a type of disaster waste generated by earthquakes and tsunamis, contain large amounts of wood chips. This residue cannot be used as ground material mainly because its bearing capacity is insufficient and the decay process of wood chips has not been well understood. In this study, unconfined compression (UC) tests were performed using two types of wood chips (fibrous cocopeat and granular hinoki), which closely resemble the under-sieve residue, with slag and Iwaki sands. The test results indicated that the UC strength of the slag mixed with cocopeat or hinoki at 10% by volume was higher than that of only slag. In addition, they indicated that the UC strength and deformation modulus of Iwaki sand mixed with cocopeat were higher than those of just Iwaki sand for cocopeat mixing ratios of less than 20% by volume.
