All the AAS pastes exhibited properties such as fast setting, good workability, and high early compressive strength. The results showed that both the silicate moduli and Na 2O contents had significant effects on the engineering properties of AAS pastes. AAS pastes were prepared using the activator with five different silicate moduli of 1, 1.2, 1.4, 1.6, and 1.8 and three different Na 2O contents of 6%, 8%, and 10%. The water-to-slag ratio of AAS paste was kept constant at 0.35 by mass. This study focused on the engineering properties of alkali-activated slag (AAS) pastes prepared by mixing an activator consisting of sodium silicate and sodium hydroxide at room temperature. ![]()
