The purpose of this study is to develop structural material which uses rice husks and rice straws effectively. Test samples were magnesium improved soils mixed with rice husk ash (RHA) and rice straw fibers (RSF). In order to develop good structure materials of an agricultural canal, there needs to examine material properties by mechanical test. The splitting test was conducted on three types of soil sample (normal, mixed with RHA, and mixed with RHA and RSF). Fracture process was qualitatively evaluated by image analysis and acoustic emission (AE). As a result, the splitting tensile strength was detected upward trend in RHA and RSF samples.
