| Recently, the treatment of coal ashes produced from thermal electric power plants have been raised as a serious problem in according to the increasing of electric power demand in Korea. This paper deals with a re -use method of coal ash as a fill material. Two domestic coal ashes are mixed with cement and lime to improve the mechanical properties of coal ash. The mechanical properties such as compressive strength, compressive deformation, permeability and frost heaving property are investigated in according to the change of admixture rate, curing temperature and curing time. In this study, it is found coal ash (fly ash+bottom ash) and fly ash with 2%~3% cement can be used as a fill material, respectively. It is also found the frost heaving properties of coal ash is effectively improved by the mixture of 6%~9% cement. |
