Abstract
Inorganic binder was made from MSWI bottom ash and blast furnace slag by geopolymer technique in this study. AS for manufacturing of inorganic binder, different MSWI bottom ash content and type of activators are investigated to obtain the optimum condition. The specimens were solidified under alkali condition and cured at 50°C. Compressive strength was measured to evaluate the characteristics of specimens for the period of 1, 3, and 7 days. XRF and XRD was also analyzed to find geopolymer matrix. The microstructure of inorganic binder prepared was analyzed by FTIR. As immobilization of heavy metals, the leaching test are employed to investigate the immobilization of the inorganic binder. TCLP method is used to environmental safety of inorganic binder.
