A-22 DENSIFICATION BEHAVIOUR OF INCINERATOR BOTTOM ASH (IBA) USING POWDER COMPACTION METHOD(Session: Inorganic Materials)

抄録

In this work, locally incinerator bottom ash (IBA) with particle size less than 290μm was processed using conventional powder production technique involving milling, compacting and sintering. Ball milling was used in order to reduce the particle size of the ash. Uniaxial compaction process was carried out to form a green parts. Then green samples were sintered at three different temperatures of 1000℃, 1050℃ and 1100℃. Characterizations were made at every single process involved; powder, green and sintered parts. From this study, it showed that the sintered product of the finer ash promotes better green and sintered quality. The sintered densities seem to be increased along temperature increment which contribute to better mechanical properties, hardness and compression strength.
