The purpose of this study was to analyze the physicochemical characteristics of bottom-ash recycling from municipal solid waste incineration (MSWI) and investigate the possibility of the use of bottom ash for Lightweight Aggregate for Structural Concrete and Bottom Ash Aggregate for Road Construction according to Korean Industrial Standards (KS). Samples were taken from the MSWI bottom ash collected at the resource recovery facilities “A” and “B.” In the results, both samples did not satisfy the criteria of the particle sizes. In particular, the two samples failed to comply with the physical and chemical characteristics criteria of the Lightweight Aggregate for Structural Concrete. On the other hand, both bottom ash samples met the physical characteristics criteria of the Bottom Ash for Road Construction. Therefore, the recycling of Bottom Ash Aggregate for Road Construction can be more a suitable method for recycling, provided that proper pre-treatment as a screening process for bottom ash is performed.
