【摘要】 随着建筑垃圾的日益增多以及天然粗骨料的过度开采,作为一种低碳、环保、绿色可持续的新型建筑材料,再生混凝土越来越受到人们的重视。但是由于再生混凝土的力学性能普遍低于一般的混凝土,从而制约了它在实际工程中的应用。本文对近年来与再生混凝土力学性能相关的研究进展进行了综述,分别就水灰比、再生粗骨料替代率、再生粗骨料改性、矿物掺和料以及纤维等方面对再生混凝土力学性能的影响进行分析,对再生混凝土进一步的研究和应用具有重要意义。更多还原

【Abstract】 With the increasing construction waste and excessive exploitation of natural coarse aggregate, recycled aggregate concrete, as a new building material of low carbon, environmental protection and green sustainability, has been paid more and more attention by people.However, the mechanical properties of recycled aggregate concrete are generally lower than that of ordinary concrete, which restricts its application in practical engineering.In this paper, the recent years with recycled aggregate concrete mechanics performance related research progress were summarized, respectively water-cement ratio and recycled coarse aggregate replacement rate, modification of recycled coarse aggregate, mineral admixture and the influence of the fiber mechanical properties of recycled aggregate concrete is analyzed, for further research and application of recycled aggregate concrete is of great significance.更多还原
