Evaluation of splitting characteristics of magnesium improved soil by image analysis

This paper shows that rice husk ash (RHA) changes the mechanical property of magnesium improved soil. Splitting test was conducted on two types of soil (normal and mixed with RHA). Fracture process was qualitatively evaluated by image analysis and acoustic emission (AE). Thus, concentration of vertical stain and AE in spitting fracture appears different characteristics. By evaluating the mechanical properties from image analysis and AE parameters, the characteristic of improved soil is qualitatively evaluated.
