Abstract
Toexplorethesplittingstrengthofexpandedpolystyrene(EPS)concretewiththedifferent
volumeconcentrationsofEPS,Braziliandiscspecimenswerediametrallyimpactedbyusinga74-mmdiametersplitHopkinsonpressurebar(
SHPB)atdifferentimpactvelocities.ForeachvolumeconcentrationofEPS,
theBraziliandiscspecimensweretestedinthecasesoftwodifferentparticlesizes
ofEPS,respectively.Andaccuratelydesignedcushionswereplacedintheinterspacesbetweentheinputandoutputbarsandthespecimenstopreventthespecimensfrombei

AndthesplittingfailurepatternsofEPSconcretewereanalyzed.Theresultsdisplaythatthe
splittingstrengthofEPSconcreteincreaseswiththeincreaseofstressrate;andthatintheEPSconcretewiththelowvolumeconcentrationofEPS,

andthiseffectdisappearsgraduallywiththeincreaseoftheEPSvolumeconcentration.
