International Conference on Alkali Activated Materials and Geopolymers: Versatile Materials Offering High Performance and Low Emissions
Fly ash (FA) and ground granulated blast -furnace slag (GGBS) are industrial wastes and have been widely utilized as construction material due to the environmental impacts. The use of these by-products is not only for the sustainable construction but also for reducing the emission of CO2 due to the use of Portland cement. This study presents the microstructure and mechanical properties of geopolymer paste made from different ratios of low -calcium FA and GGBS after exposure at elevated temperature (500- 950oC). Compressive strength tests for both heated and unheated cylindrical specimens (using 50 mm x 100 mm …
