摘?要:研究了劍麻纖維活性粉末混凝土的流動度和力學性能,并在試驗的基礎上,就劍麻纖維對活性粉末混凝土延性和脆性的改善效果進行了量化計算。結果表明,隨著劍麻纖維摻量從0增加到1.6%,活性粉末混凝土的流動度、抗壓強度和抗折強度分別降低了36%、9%和13%;劍麻纖維的摻入使得混凝土的跨中位移和開口位移極限值分別增加了47%和42%,斷裂能和延性指數分別提高了19%和35%。Abstract:Thefluidityandmechanicalpropertiesofreactivepowderconcrete(RPC)withsisalfiberwerestudied,andonthebaseofexperimentalanalysis,theimprovementeffectofsisalfiberontheductilityandbrittlenessofRPCwascalculated.Theresultsshowthatwiththeincreaseofsisalfiberdosagefrom0to1.6%,thefluidity,compressivestrengthandflexuralstrengthofRPCdecreaseby36%、9%and13%respectively.Theadditionofsisalfiberresultsintheincreaseoflimitvaluesofmid-spandisplacementandopeningdisplacementofRPCby47%and42%respectively,andthefractureenergyandductilityindexincreaseby19%and35%respectively.
