소각비산재를 무기결합제로 제조시 활성필러 분말도에 따른 압축강도 특성

초록

Characteristics of compressive strength of inorganic binder made from MSWI fly ash was analyzed with the change of fineness of blast furnace slag in this study. 4,000 ~ 8,000 cm²/g of slag was used. Mixing ratio of fly ash was obtained under the condition of 20wt% of fly ash and 6,000 cm²/g of slag. Specimen was analyzed to verify the formation of geopolymer by XRD, SEM and FTIR. According to the results, aluminosilicate was found in it. It means that geopolymer matrix is formed. And it was tested to evaluate environmental safety by Korea Standard Leaching Test (KSLT). It is possible to prepare inorganic binder with the use of MSWI fly ash and blast furnace slag.
