The　fluidized　bed　combustion　(FBC)　ash　was　evaluated　for　value-added　use　in　the　production　of　geopolymer　concrete　where　alkali　aluminosilicate　hydrates　are　the　primary　binder　constituents.　The　FBC　was　supplemented　with　other　raw　materials　in　order　to　achieve　chemical　balance,　and　they　were　milled　with　CO2　and　air　to　evaluate　the　benefit　from　CO2　uptake.　An　experimental　study　on　the　properties　of　the　optimum　FBC　ash-based　hydraulic　cement　and　the　concrete　fabricated　from　it　was　conducted.　Also,　the　corresponding　properties　of　Portland　cement　concrete　were　also　investigated　as　the　reference　group.　For　the　FBC　ash-based　cement,　tests　were　performed　to　measure　the　CO2　uptake　and　heat　of　hydration;　for　FBC　ash-based　hydraulic　cement　concrete,　measurements　were　made　on　the　compressive　strength　of　hardened　material,　residual　compressive　strength　after　immersion　in　boiling　water　and　sulfates　resistance.　The　results　of　this　study　suggest　that,　the　FBC　ash-based　geopolymer　with　the　mechanicochemical　aviation　can　provide　desired　mechanical　attributes,　sulfates　resistance　when　compared　with　normal　Portland　cement　concrete.　©　2018　Institute　of　Physics　Publishing.　All　rights　reserved.
