Geopolymer foam block was prepared and its characteristics discussed to evaluate the possibility of replacing blastfurnace slag (below BFS) with melting slag in this study. 10~20wt% of BFS was replaced with melting slag. And also10wt% of mine tailing was replaced with fly ash discharged from municipal solid waste incinerator (below MSWI). Thecompressive strength of foam block prepared was similar to that of foam block prepared without replacing BFS. Andalso it was increased by replacing 10wt% of mine tailing with MSWI fly ash. Considering these results, melting slagmay be used instead of BFS without damaging the quality of foam block.
