| 摘 要： | 研究不同再生粗骨料取代率混凝土棱柱体轴心抗压强度和立方体抗压强度的关系,在掺入减水剂与不掺减水剂两种配合比下再生粗骨料的取代率分别为0、30%、50%和100%。试验结果表明,再生混凝土轴心抗压强度比相同条件下的普通混凝土轴心抗压强度偏小,且随着再生粗骨料取代率的增加而减小。

| Abstract: | The relationship between axial compressive strength and cube compressive strength of recycled aggregate concrete was discussed in the paper with different recycled coarse aggregate replacement ratio. The percentages of recycled coarse aggregate were 0,30% ,50% ,and 100% in the condition of having water-reducing agent and the condition without water-reducing agent. The experimental results show that the axial compressive strength of recycled aggregate concrete was smaller than the axial compressive strength of ordinary concrete under the same conditions. The axial compressive strength of recycled aggregate concrete would decrease when the recycled coarse aggregate replacement rate increases. |
