Environmental degradation and increased greenhouse gas emissions force communities to achieve sustainable green building and construction materials. The environmental and financial aspects of sustainable development and circular economy strongly depend on the recycling of wastes into new products. Geopolymers gained increasing attention because of their eco-friendly and superior mechanical characteristics and their ability to utilize numerous wastes as precursors. Although there are numerous studies on geopolymer, little attention was focused on geopolymer concrete (GeoC). Hence, This review follows the Preferred Reporting Items for Systematic Reviews (PRISMA) investigated in detail GeoC. The first part of this study explores the recent synthesis processes, different precursors, and applications of geopolymer concrete (GeoC) in numerous sectors as well as the mechanical, microstructural, and physical related characteristics of GeoC developed from various wastes. The second part discusses in detail the contributions of GeoC to the sustainable development goals (SDGs) stated by the United Nations. The last part discusses the implementation of different wastes to develop GeoC-based circular economy to provide recommendations and prospects for GeoC science and technology. An eco-friendly, sustainable, structurally sound GeoC matrixes can be developed from numerous industrial, municipal, and agricultural wastes. Such GeoC is a good candidate to traditional concrete and some other building materials. GeoC is strongly contribute into 12 SDGs of the main 17 SDGs. Optimizing the elements of GeoC would decrease its cost and thus promote a green circular economy.
环境恶化和温室气体排放增加迫使社区实现可持续的绿色建筑和建筑材料。可持续发展和循环经济的环境和财务方面强烈依赖于将废物回收为新产品。由于其环保和优越的机械特性以及能够利用多种废物作为前体，地质聚合物受到了越来越多的关注。尽管有许多关于地质聚合物的研究，但很少有人关注地质聚合物混凝土（GeoC）。因此，本综述遵循系统评价的首选报告项目（PRISMA），详细研究了 GeoC。本研究的第一部分探讨了地质聚合物混凝土（GeoC）的最新合成工艺、不同前体以及在众多领域的应用，以及从各种废物开发的 GeoC 的机械、微观结构和物理相关特性。第二部分详细讨论了 GeoC 对联合国提出的可持续发展目标（SDGs）的贡献。最后一部分讨论了实施不同废物以开发基于 GeoC 的循环经济，为 GeoC 科学和技术提供建议和展望。可以从众多工业、市政和农业废物中开发出具有生态友好性、可持续性和结构稳定性的 GeoC 基质。这种 GeoC 是传统混凝土和其他一些建筑材料的良好替代品。GeoC 强烈有助于实现主要的 17 个可持续发展目标中的 12 个目标。优化 GeoC 的元素可以降低成本，从而促进绿色循环经济。
