抄録: Coal ash produced at the thermal power plants is one of the largest source of waste materials in Japan. Due to environment protection and increasing problems of the disposing of coal ash, there are important reasons for its effective utilization for earth work problem. This paper deals with the general properties of coal ash and the laboratory investigations on the effective utilization of coal ash for earth work problem. Specific earth work problems are included light-weight fill and subgrade on the soft clay ground. Laboratory investigation was carried out unconfined compression tests and penetration tests on the specimen (called EPS Ash) mixed with coal (fly) ash, expanded polystyrol beads, portland cement and water with various conditions of mix proportion, curing method and curing time. From the results of laboratory testing of EPS Ash, optimum mix proportion and curing time for light-weight fill and subgrade were determined.
