In this study, geopolymer is synthesized from co-combustion product of bamboo and kaolin with KOH solution as activator. For comparison, geopolymer is also synthesized from mixture of bamboo ash and metakaolin that combusted separately. Characterization of obtained geopolymer comprises compressive strength, phase analysis by X-ray diffraction, functional group analysis by Fourier transform infrared spectroscopy, and microstructure by scanning electron microscopy. Geopolymer from co-combustion product has compressive strength which is slightly lower compared to geopolymer from mixture of bamboo ash-metakaolin; but their characteristics covering mineral phase, functional group, and microstructure are almost the same.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Bamboo ash,Co-combustion,Geopolymer,Metakaolin,Portland cement[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1166/asl.2017.8813[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
