Abstract

Ordinary Portland cement is the most popular binding material for any construction work. Geopolymer is emerging as a new alternative binding material. GPC has a variety of benefits, including enhanced strength and durability characteristics. The GPC's high early-age strength and ambient curing contribute to a shorter building period. Examples of such factors are alkali-activated solutions, binder materials, and curing techniques. Control the strength attributes of GPC. Additionally, the addition of industrial wastes like fly ash and ground Granulated Blast-Furnace Slag (GGBS) to GPC has benefits like lower carbon dioxide emissions, the capacity to reuse waste materials, preventing the conversion of precious areas into dump yards, lower costs, and so on. Additionally, less energy is needed to retrieve raw minerals from the ground.

This paper comprehensively reviews GPC's early hydration and strength development properties, mix design procedure, and structural performance. In addition, it illustrates how high-strength GPC was developed using fly ash and metakaolin as an alkaline solution under typical curing conditions and temperatures. Trial and error techniques are suggested for developing GPC from various binder ingredients. For fly ash-based GPC, Rangan's mix design process is employed. Additionally, it was discovered that adding fibres enhances the malleable quality of GPC. Future GPC-related research ideas and directions are also included.
