In the global construction industry, with the growth of population, two important construction problems have to be faced, namely, the excessive consumption of non-renewable resources and the massive accumulation of construction waste. In order to solve these problems, geopolymer recycled aggregate concrete (GRAC) arises at the historic moment. On the one hand, using geopolymers produced by industrial wastes to completely or partially replace cement can reduce cement consumption, thus reducing CO 2 emissions. On the other hand, recycled concrete made of recycled aggregate can consume accumulated construction waste and save non-renewable materials and land resources. The combination of the two materials can protect the environment to the greatest extent and save resources. This article reviews the current research on the mechanical properties of GRAC, makes a systematic analysis of GRAC materials, reaction mechanisms, and evaluation indicators, and also discusses the application prospects of GRAC, and strives to make contributions to the field and industry.

地聚合物再生骨料混凝土力学性能的研究进展

在全球建筑业中，随着人口的增长，必须面对两个重要的建筑问题，即不可再生资源的过度消耗和建筑垃圾的大量积累。为了解决这些问题，在历史时刻出现了地聚合物再生骨料混凝土（GRAC）。一方面，使用工业废物产生的地质聚合物完全或部分替代水泥可以减少水泥消耗，从而减少CO 2排放。另一方面，由再生骨料制成的再生混凝土可以消耗累积的建筑废料并节省不可再生的材料和土地资源。两种材料的结合可以最大程度地保护环境并节省资源。
