Applicability of molten slag originated from domestic wastes to fine aggregate for concrete was studied. Monthly changes in quality of the molten slag were taken into account and the quality of the resulting concrete, when applied to a full-scale structure, was examined in terms of fresh and hardened properties. It was found that the quality variation of the molten slag, as a fine aggregate, was sufficiently small during 8-month inspection and was within the range of TR A 0016: 2002. A molten slag fine aggregate concrete, with a water-cement ratio of 0.45 and Air Entraining and high-range water reducing agents, showed nearly the same performances, Including pumpability, compressive strength and concrete quality in structure, as those of the normal concrete.
