Abstract
The technology behind geopolymer mortar allows for the creation of mortar made from recycled materials that are less harmful to the environment. High-temperature curing treatment is required for typical GGBS based geopolymer mortar in order to achieve acceptable early strength characteristics; this is a significant constraint for cast-in-place mortar applications. Pre-hardened by heat curing, the characteristics of geopolymer mortar have been the primary focus of most past research. Geopolymerization reactions might produce stronger results if they are cured for longer and at the ideal temperature. Thus, geopolymer mortars based on ground granulated blast furnace slag (GGBS) were made by curing them at 60, 80 and 100°C for 6, 12 and 24 hr, respectively. Sodium silicate and sodium hydroxide solutions served to activate the GGBS. Sodium silicate and alkaline activator were mixed at a ratio of 1:3. In this case, the data demonstrate that curing at 100°C for 24 hr provided the best compressive strength.
