Abstract：Topromotetheapplicationofultra-high-strengthconcrete（UHSC）inroofing waterproofingsystems，the fectsof fiberand water-repelentagentaditionsonthemechanicaland waterprofpropertiesofUHSCwereinvestigated.Theresults indicatetattheflexuralstrengthoftheconceteispositivelycorelatedwithfibercontent，reachingoptimalflexuralstrengthand impermeability when the fiber dosage is .Conversely，the addition of the water-repellent agent is inversely correlated with both water absorption and flexural strength. At a dosage of ，the UHSC exhibits superior compressive strength and water absorption properties.
