摘要:
通过立方体抗压强度试验,研究了再生细骨料取代率对再生混凝土抗压强度的影响。结果表明:当再生细骨料取代率小于30%时,再生细骨料对再生混凝土的抗压强度影响不大; 当再生细骨料取代率大于30%时,再生混凝土的抗压强度明显降低; 当再生细骨料取代率为100%时,再生混凝土的抗压强度只达到普通混凝土抗压强度的61%; 掺入再生细骨料后,再生混凝土抗压强度的离散性变化较大,当再生细骨料取代率在0%～100%时,再生混凝土的抗压强度标准差在1.36～4.17 MPa之间。
Abstract:
Authors studied the effects of the recycled fine aggregate(RFA)replacement ratio on compressive strength of recycled concrete through cubic compressive strength experiment. The result shows that there is little effect on the compressive strength of recycled concrete when the RFA replacement ratio is less than 30%; the compressive strength of recycled concrete is reduced when the RFA replacement ratio is more than 30%. When the RFA replacement ratio is 100%, the compressive strength of recycled concrete is 61% than that of ordinary concrete. There is a significant change in the discreteness of the compressive strength of recycled concrete after the RFA is mixed. The standard deviation of the compressive strength of recycled concrete is between 1.36 MPa and 4.17 MPa when the RFA replacement ratio varies from 0% to 100%.
