摘要:
在再生粗骨料取代率为70%的基础上，研究经碳化强化处理的再生细骨料对再生混凝土基本力学性能的影响规律。并与未碳化再生细骨料的情况进行对比，再生细骨料的取代率为0、20%、30%、40%。实验结果表明：再生混凝土抗压强度随再生细骨料取代率提高而减小，碳化再生细骨料可提高再生混凝土抗压强度。
Abstract:
Based on the replacement rate of recycled coarse aggregate which was 70%, the effects of recycled fine aggregate treated by carbonization on the basic mechanical properties of recycled concrete were studied. The replacement rate of recycled fine aggregate was 0, 20%, 30%, 40%, and the condition of fine aggregate was compared with that of non-carbonated recycled fine aggregate. Experimental results show that the compressive strength of recycled concrete decreases with the increase of the replacement rate of recycled fine aggregate, and the carbonated recycled fine aggregate can improve the compressive strength of recycled concrete.
