摘　　要：　基于大量相关文献的分析研究,本文较为全面地介绍了国内外关于再生混凝土抗压强度特征的研究成果。主要包括再生混凝土抗压强度较普通混凝土的变化,再生混凝土抗压强度的变异特性,再生混凝土抗压强度与水灰比的关系,再生混凝土抗压强度随龄期的发展规律,再生骨料强度以及再生骨料取代率对再生混凝土抗压强度的影响。在此基础上,提出了关于再生混凝土抗压强度需要进一步研究的问题。Based on enough related references,an extensive review on the characteristics for eompressive strength of recycled aggregate concrete is presented in this paper.The changing of the compressive strength from that of normal concrete, the characteristics of variation of compressive strength,the relationship between the compressive strength with the water/cement ratio,the development of the compressive strength with age and the influence of the strength of recycled aggregate and the recycled aggregate replacement ratio on it.Finally,some recommendations for further studies on the compressive strength of recycled aggregate concrete are put forward.
