Popis: The treatment of coal ash produced at coal-fired power plants requires high costs and has environmental problems. Therefore, a high proportion of coal ash has been reused, and the effective reuse of coal ash has been investigated extensively. In this study, the physical-chemical characteristics of bottom ash and fly ash sampled from a domestic coal-fired power plant were investigated. In addition, the shear behavior of bottom and fly ashes-sand mixtures was evaluated to verify the reuse potential of bottom and fly ashes. Direct shear tests were performed to evaluate the friction angle of the coal ash-sand mixture, which was used as an input parameter in the numerical analysis for slope stability to establish a framework for assessing the reuse potential of coal ash.
