摘 要：通过正交试验研究了纳米CaCO3掺量、水胶比、砂率和再生粗骨料掺量对再生混凝土抗压强度的影响。结果表明，影响再生混凝土7d抗压强度的主要因素是水胶比，而影响再生混凝土14d和28d抗压强度的主要因素是再生粗骨料掺量。此外，适量纳米CaCO3能够改善再生混凝土的抗压强度，其对早期抗压强度的提高更加明显。Abstract:Theeffectsofnano-CaCO3content,water-binderratio,sandratioandrecycledcoarseaggregatecontentonthecompressivestrengthofrecycledconcretewerestudiedbytheorthogonaltest.Theresultsshowthatthemainfactoraffecting7dcompressivestrengthofrecycledconcreteisthewater-binderratio,whilethemainfactoraffecting14dand28dcompressivestrengthofrecycledconcreteisthecontentofrecycledcoarseaggregate.Inaddition,thecompressivestrengthofrecycledconcretecanbeimprovedbyaddingtheappropriateamountofnano-CaCO3,andwhichismoreobviousfortheearlycompressivestrength.

摘 要：研究了剑麻纤维活性粉末混凝土的流动度和力学性能，并在试验的基础上，就剑麻纤维对活性粉末混凝土延性和脆性的改善效果进行了量化计算。结果表明，随着剑麻纤维掺量从0增加到1.6%，活性粉末混凝土的流动度、抗压强度和抗折强度分别降低了36%、9%和13%；剑麻纤维的掺入使得混凝土的跨中位移和开口位移极限值分别增加了47%和42%，断裂能和延性指数分别提高了19%和35%。Abstract:Thefluidityandmechanicalpropertiesofreactivepowderconcrete(RPC)withsisalfiberwerestudied,andonthebaseofexperimentalanalysis,theimprovementeffectofsisalfiberontheductilityandbrittlenessofRPCwascalculated.Theresultsshowthatwiththeincreaseofsisalfiberdosagefrom0to1.6%,thefluidity,compressivestrengthandflexuralstrengthofRPCdecreaseby36%、9%and13%respectively.Theadditionofsisalfiberresultsintheincreaseoflimitvaluesofmid-spandisplacementandopeningdisplacementofRPCby47%and42%respectively,andthefractureenergyandductilityindexincreaseby19%and35%respectively.
