Abstract：Toinvestigatetheinfluenceofdiferentcuring methodsonthe strengthofgeopolymerconcrete.Through experiments， thecompresivestrengthof geopolymerconcretewith diffrent water-glueratiosand diferentstel fibercontentunderfour conditions：standard curing，filmcuring，dry aircuring and combined curing were studied，and the hydration behavior of the concretewascomparedandanalyzed from the microscopicscale.Theresultsshow thatthe hydrationreactionof geopolymer concretecanbeefectively promoted intheearlystageof standardcuringandfilmcuring，andadensergel structurecanbe formed，therebysignificantlyimprovingthecompresivestrength.Dryaircuring leadstoincompletehydration，increased porosity，andrelativelylowcompressivestrengthduetorapidevaporationofwater.Theinitialcuringconditionshadasignificant impactonthesubsequent strengthdevelopment，andthespecimens that wereconverted todryaircuring after3days of film curing had thebest strengthdevelopmentcomparedwithother groups.Thelow water-glueratioand the incorporationof steel fibers alsoplayanimportantroleinthecompresive strengthof geopolymerconcrete.Research findingscanprovidereferences for related applications.
