The depletion of aggregate-related natural resources is the primary concern of all researchers globally. Recent studies emphasize the significance of recycling and reusing various types of natural or by-product material waste from industry as a result of the building industry's rising demand for aggregate as the primary component in concrete production. It has been demonstrated that the geopolymer system has exceptional features, such as high strength, superior durability, and greater resistance to fire exposure, making it a viable alternative to ordinary Portland Cement (OPC) concrete. This study will examine the present method utilized to generate artificial aggregate-based geopolymers, including their physical and mechanical properties, as well as their characterization. The production process of geopolymer derived from synthetic aggregates will be highlighted. In conjunction with the bonding of aggregates and the cement matrix, the interfacial transition zone (ITZ) is highlighted in this work as an additional important property to be researched in the future. It will be discussed how to improve the properties of geopolymers based on artificial aggregates. It has been demonstrated that cold bonding provides superior qualities for artificial aggregate while conserving energy during production. The creation of ITZ has a significant impact on the bonding strength between artificial aggregates and the cement matrix. Additionally, improvement strategies demonstrate viable methods for enhancing the quality of manufactured aggregates. In addition, other recommendations are discussed in this study for future work.
与骨料相关的自然资源枯竭是全球所有研究人员主要关注的问题。近期研究强调了回收和再利用工业中各种天然或副产品材料废料的重要性，这是由于建筑行业对作为混凝土生产主要成分的骨料的需求不断增加。事实证明，地质聚合物体系具有卓越的特性，如高强度、优异的耐久性和更强的耐火性，使其成为普通硅酸盐水泥（OPC）混凝土的可行替代品。本研究将考察目前用于生产人造骨料基地质聚合物的方法，包括其物理和力学性能以及特性表征。将重点介绍由合成骨料衍生的地质聚合物的生产过程。结合骨料与水泥基体的粘结，本研究强调界面过渡区（ITZ）是未来有待研究的另一项重要性能。将讨论如何改善基于人造骨料的地质聚合物的性能。事实证明，冷粘结为人造骨料提供了优异的性能，同时在生产过程中节约了能源。ITZ的形成对人造骨料与水泥基体之间的粘结强度有重大影响。此外，改进策略展示了提高人造骨料质量的可行方法。此外，本研究还讨论了未来工作的其他建议。
