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：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7 d抗压强度的主要因素是水胶比，而影响再生混凝土14 d和28 d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: The effects of nano-CaCO₃ content, water-binder ratio, sand ratio and recycled coarse aggregate content on the compressive strength of recycled concrete were studied by the orthogonal test. The results show that the main factor affecting 7 d compressive strength of recycled concrete is the water-binder ratio, while the main factor affecting 14 d and 28 d compressive strength of recycled concrete is the content of recycled coarse aggregate. In addition, the compressive strength of recycled concrete can be improved by adding the appropriate amount of nano-CaCO₃, and which is more obvious for the early compressive strength.
