Analysis of Fly Ash and GGBS-based Geopolymer Concrete under Different Curing Conditions
This research explores how changes in the amount of activator, curing methods, and the type of starting materials affect the characteristics of geopolymer concrete (GPC). Concrete mixtures were made using various ratios of fly ash, ground granulated blast furnace slag (GGBS), and sodium hydroxide (NaOH) solutions of different concentrations (8, 10, and 12M), and then cured under normal room temperature, heat, and steam conditions. The initial properties of the concrete were measured with a slump test, and the properties that had been fully set, such as the ability to withstand compression, split tensile strength, and bending strength, were tested at 7, 14, and 28 days. The findings indicate that increasing the concentration of NaOH and using steam for curing greatly enhances the strength of GPC, with the best-performing mix of fly ash and GGBS. A cost analysis comparing GPC with standard Portland cement concrete (PCC) indicates that while GPC has higher initial costs, it offers superior durability and environmental benefits.
