영문 초록

The main objective of this study was to evaluate the effects on shape and size, compressive strength, water absorption and heavy metals leaching with various weight mixing ratios in waste ash brick products using waste recycJing MSWI(Municipa1 Solid Waste Incinerator) bottom ash, steel slag and waste building materia1. ηle manufacturing processes for the waste ash brick consist of scrε， ening， mixing, conveyor transmission, compaction forming, and curing steps of raw materials. The weight mixing ratios of steε1 slag around bottom ash were adjusted within the ranges of 10% to 30%. The reported rε， sults show that the width and thickness of the manufactured waste ash brick could be satisfied with 90 :t 2 mm and 57 :t 2 mm, respectivεly which are K.S. standards of products qualities. And in case of length, only 20-Ba50Ss30, 20-Ba60Wb20 d 20-Ba50Wb30 for the mixing ratios could be satisfied with 190 :t 2 mm that is K.S. standards of products quality. The compressive strength and water absorption for 20-BOSs30 20-Ba70WblO were over 8 N/mm2 and below 15% respectiveJy that are K.S. standards of manufactured waste ash brick. The rδ， sults of tests for the heavy metals leaching in the a11 manufactured wastε ash bricks are a1so passed to the wastes management regulations. The cost analysis of 20-Ba50Ss30 is eva1uated. The manufacturing cost is eva1uated 34.3 wonlbrick with 8 hours and 20tons of raw material pεr day. Incinerators with problems in bottom ash disposal can therefore derive significant benefits from the application of waste ash brick production.
