Clay-based geopolymer material cement is an intriguing alternative to traditional Portland cement when looking for ecologically friendly and sustainable building materials. This material blends cutting-edge geopolymerization technologies with abundantly available clay to produce a variety of advantages, including enhanced mechanical properties and reduced carbon emissions. As the need for green building solutions grows, clay-based geopolymer cement stands out because of its superior structural performance, durability, and resistance to extreme environmental conditions. In this study, we present a complete examination of the curing conditions, structural features, and diverse applications of geopolymers, emphasizing the essential elements that determine their strength and performance. We investigated the effect of curing temperature and duration, demonstrating that favorable curing temperatures (such as 60-80 °C) can increase the strength of geopolymers, whereas excessive curing temperatures can degrade their long-term structural integrity. Pre-curing treatments, such as heat and moisture management, were also investigated for their capacity to improve the microstructural density and minimize the porosity. In addition, we investigated improved curing procedures such as autoclave and steam-saturated methods, which provide higher mechanical qualities, especially in terms of compressive strength. Herein, we discussed a variety of applications, including high-performance composites in aerospace and construction and environmental remediation employing the capacity of geopolymers to immobilize dangerous compounds. Finally, we addressed the promise of geopolymers in future sectors, such as infrastructure repair, environmentally friendly systems, and applications in medicine, emphasizing their long-term viability and versatility in current materials science.
在寻找生态友好型和可持续建筑材料时,基于粘土的地质聚合物材料水泥是传统波特兰水泥的一个有趣替代品。这种材料将前沿的地质聚合技术与大量可得的粘土混合,产生了多种优势,包括增强的机械性能和减少的碳排放。随着对绿色建筑解决方案需求的增长,基于粘土的地质聚合物水泥因其卓越的结构性能、耐久性和对极端环境条件的抵抗力而脱颖而出。在本研究中,我们对地质聚合物的养护条件、结构特征和多样应用进行了全面考察,强调了决定其强度和性能的关键要素。我们研究了养护温度和持续时间的影响,证明适宜的养护温度(如60 - 80°C)可提高地质聚合物的强度,而过高的养护温度会损害其长期结构完整性。还研究了诸如热和湿度管理等预养护处理对改善微观结构密度和最小化孔隙率的能力。此外,我们研究了如高压釜和蒸汽饱和法等改进的养护程序,这些方法能提供更高的机械性能,尤其是在抗压强度方面。在此,我们讨论了多种应用,包括航空航天和建筑领域的高性能复合材料,以及利用地质聚合物固定危险化合物能力的环境修复。最后,我们探讨了地质聚合物在未来领域的前景,如基础设施修复、环保系统和医学应用,强调了它们在当前材料科学中的长期可行性和多功能性。
