An Experimental Investigation on Geopolymer Concrete Blended with Alccofine Cured Under Heat and Ambient Condition

Abstract - This study investigates the effects of Alccofine on the properties of geopolymer concrete cured under heat and ambient conditions. Geopolymer concrete specimens were prepared with varying proportions of Alccofine and cured at different temperatures. The results show that Alccofine improves the compressive strength, durability, and workability of geopolymer concrete. Heat curing enhances the early- age strength of geopolymer concrete, while ambient curing allows for slower strength development. The findings suggest that geopolymer concrete blended with Alccofine has potential applications in sustainable construction, particularly in projects requiring high strength and durability.Geopolymer concrete, an eco-friendly alternative to conventional Portland cement concrete, is synthesized using industrial by-products such as fly ash, activated by alkaline solutions. Alccofine, known for its ultrafine particle size and high reactivity, is introduced into the mix to enhance the mechanical and durability properties of GPC. The research evaluates the influence of different curing regimes—heat curing and ambient curing—on compressive strength, setting time, and microstructural characteristics. Results demonstrate that Alccofine significantly contributes to early strength development, particularly under heat curing, while also improving long-term performance under ambient conditions.
