Domestic waste molten slag can be recycled into fine aggregate for concrete. The recycling process comprises heating, melting, cooling, solidification and secondary processing where influences of the furnace type at the heating and melting processes on the quality of molten slag and molten slag concrete are still unknown. We have studied the physical properties of molten slag obtained from furnaces of various type and behavior of molten slag concrete to clarify the effects of furnace type. Domestic waste molten slags generally met the quality requirements though it exhibited various characters according to the furnace type and the level of secondary processing. Also the molten slag concrete satisfied the specified quality when fine aggregates of domestic waste molten slag were used without regard to the furnace type.
