摘　　要：为了妥善处理建筑垃圾对环境以及资源利用的影响,再生混凝土应用是一种较为可行的解决方案。然而却由于其自身的性能存在某些缺陷,使其在工程中未能大量应用。本文通过对国内外大量有关外加剂对再生混凝土性能影响研究成果的分析,探讨外加剂对再生混凝土性能的改善方式,并展望再生混凝土性能研究的发展方向。分析认为:再生混凝土中加入适量的减水剂,对其抗压强度、和易性能及弹性模量都有所改善;防冻剂可以改善其抗冻性能。为此可以进一步研究外加剂对再生混凝土性能的影响,以更好改善其投入实际工程的适用性。In order to properly deal with the influence of construction waste on the environment and the utilization of resources, the application of recycled concrete is a feasible solution. However, due to its own performance, there are some defects, so that it can not be applied to a large number of applications in the project. Through analysis of domestic and foreign large amount of additive on performance of recycled concrete influence study, of additive on the properties of recycled concrete improvements, and prospects the development direction of the research on concrete performance regeneration. It is concluded that the recycled concrete adding an appropriate amount of water reducing agent, can improve the results of the compressive strength, easy performance and elastic modulus; antifreeze agent can improve the frost resistance. To this end, In order to improve the applicability of the practical engineering, we can further study the effect of additives on the performance of recycled concrete.
