Shirasu, a pyroclastic flow deposit, is used as aluminosilicate in producing geopolymer. Ground granulated blast furnace slag is used as an admixture for development of higher initial strength of Shirasu geopolymer. Sodium hydroxide and sodium silicate solution are used as alkaline activators. Mortars are atmospheric cured or oven dry heat cured for 24 hours. Compressive strength and sulfuric acid immersion tests are carried out. Based on the experimental study, it was observed that the initial and long term strength development of Slag-Shirasu geopolymer improved and acid resistance increased.
