In order to investigate the feasibility of municipal solid waste incineration ash melted slag powder as admixture, an experimental study was performed on cement mortar with municipal solid waste incineration ash melted slag powder. Fresh mortar properties and strength properties with various municipal solid waste incineration ash melted slag powder replacement ratios were estimated. There replacement ratio adopted in this study was 0, 10, 20, 30, 40, 50%. After then flow properties was considered as properties of fresh mortar. And compressive strength was determined 3, 7, 14, 28, 56 days for the hardened mortar specimens. According to the test results, the flow of mortar was increased with in replacement amount of municipal solid waste incineration ash melted slag powder. Furthermore, compressive strength at early age was decreased, whereas the compressive strength at the age of 28, 56day was increased.
