Key findings include the impact of ultrafine Ground Granulated Blast furnace Slag (GGBS) on enhancing workability and reducing setting times. GPC exhibits lower density and improved water resistance compared to traditional concrete, with compressive, flexural, and split tensile strengths increasing over time. Microstructural analyses highlight denser matrices and improve mechanical properties through effective activation processes. These advancements highlight GPC's potential as a sustainable and durable construction material, emphasizing the need for further research and development for widespread adoption in the industry. The review categorizes frequently employed precursors based on their primary chemical components and explores how different binder types impact various aspects of lightweight geopolymers. Additionally, it consolidates optimal mix designs from various studies to aid readers in choosing suitable binders and achieving desired density and compressive strength goals through the utilization of different precursors, alkaline binder solutions, and lightweight concrete. https://ceij.ut.ac.ir/article_99384_dbaa2b95ad2abf81e5c7f7cf72ebd04d.pdf
