Ferroaluminate　cement　has　the　characteristics　of　energy　conservation,　waste　utilization,　emission　reduction,　excellent　process　performance　and　environmental　friendliness,　and　has　gradually　attracted　the　research　interest　of　scholars　at　home　and　abroad.　This　article　compared　the　hydration　processes　of　three　different　cement　systems,　namely　ferroaluminate　cement　(FAC),　sulfoaluminate　cement　(SAC),　and　Portland　cement　(PC),　through　test　methods　such　as　hydration　heat,　XRD,　TG-DTG,　pore　structure　analysis,　and　SEM.　The　hydration　products　and　mechanisms　of　three　types　of　cement　were　analyzed.　The　results　show　that　the　1　d　strength　of　FAC　increases　by　130%　compared　to　PC,　and　the　28　d　strength　exceedes　SAC.　The　hydration　heat　release　of　FAC　and　SAC　is　mainly　concentrated　within　1　d,　and　the　iron　phase　in　FAC　clinker　can　shorten　the　acceleration　period　and　promote　the　formation　of　ettringite.　Compared　with　PC　and　SAC,　FAC　hydration　products　contain　not　only　ettringite,　hydrated　calcium　silicate　gel　and　aluminum　glue,　but　also　ettringite　and　iron　glue,　with　lower　total　porosity,　more　compact　structure　of　cement　stone,　and　further　improved　strength　and　durability.　©　2024　Bulletin　of　the　Chinese　Ceramic　Society　Press.　All　rights　reserved.
