Abstract：Flyash-slag-basedgeopolymerwassynthesizedusingasodiumsilicate-sodiumhydroxidecompositealkalineactivator. Theeffectsofthemodulusofsodiumsilicateonthemechanicalproperties，fluidity，reactionmechanism，andmicrostructural characteristicsofthealkali-activatedflyash-slaggeopolymerwereinvestigatedthroughcompresiveandflexuralstrengthtests， fluiditymeasurements，scanning electronmicroscopy（SEM），andX-raydifraction（XRD）analysis.Theresearch findingsindicate thatwithanincreaseinthewaterglassmodulus，thecompresivestrength，flexuralstrength，andflowabilityofthespecimens exhibitatrendofintllyincreasingandtendecreasingTehydrationproductsoftheflyash-slaggeopolymersprimarilycoprise SiO2 ，hydratedcalciumsilicategel（C-S-H），hydratedcalciumaluminosilicategel（C-A-S-H），hydratedsodiumaluminosilicate gel（N-A-S-H）and mullite （ Al6Si2O13 ）.
