Rapid urbanization, industrialization, and economic expansion are driving up demand for cement-based products, particularly concrete, resulting in high levels of greenhouse gas emissions and climate change. This instigated investigators to look for environmentally sustainable materials to replace conventional concrete, like geopolymer concrete (GPC). Moreover, despite four decades of extensive research on GPC, it has yet to be commercialized. This article presents a review explaining the need for GPC, as well as its sustainability benefits, and commercialization challenges and strategies. The sustainability analysis includes applications, cost-effectiveness, and environmental friendliness of GPC. The commercialization challenges deal with inconsistent material characterization and performance of GPC; complex transformation of the cement industry; and conflicting economic and environmental parameters of GPC. Finally, commercialization strategies describe the implementation of emission control policies, design codes and specifications, and awareness among people regarding GPC. It is concluded that geopolymeric materials have a wide range of applications owing to their environmental friendliness, higher strength, and enhanced endurance. However, comprehensive research is required to understand the inconsistencies in the performance of GPC prepared with similar constituents. Moreover, the bulk nonavailability of waste aluminosilicate sources with similar properties to be used in GPC is another major challenge, which may increase the cost and inconsistent performance of GPC. Of the different commercialization strategies discussed, the formulation of design codes and specifications is the most important strategy to commercialize GPC. This article will lay a strong foundation for future research that will work in a specific direction to eliminate conflicting views regarding the performance standards of GPC and disseminate a positive perception of GPC among stakeholders.

地质聚合物混凝土的可持续性效益和商业化挑战与策略:综述

快速的城市化、工业化和经济扩张正在推高对水泥基产品的需求,尤其是混凝土,导致温室气体排放和气候变化的高水平。这促使研究人员寻找环境可持续的材料来取代传统的混凝土,如地质聚合物混凝土(GPC)。此外,尽管对 GPC 进行了 4 年的广泛研究,但它尚未商业化。本文介绍了一篇综述,解释了 GPC 的必要性、可持续性优势以及商业化挑战和战略。可持续性分析包括 GPC 的应用、成本效益和环境友好性。商业化挑战涉及 GPC 不一致的材料表征和性能;水泥行业的复杂转型;GPC 的经济和环境参数相互矛盾。最后,商业化战略描述了排放控制政策、设计规范和规范的实施,以及人们对 GPC 的认识。得出的结论是,地质聚合物材料由于其环境友好、强度高、耐久性强等优点而具有广泛的应用。然而,需要进行全面的研究来了解用类似成分制备的 GPC 的性能不一致。此外,在 GPC 中使用的具有相似性质的废铝硅酸盐源的大量无法获得是另一个主要挑战,这可能会增加 GPC 的成本和不一致的性能。在讨论的不同商业化策略中,设计规范和规范的制定是 GPC 商业化的最重要策略。
