N2 - Obtaining a consistent performance of geopolymer concrete for structural application is not simple. It is influenced by the main material, alkali activator, chemical additive, etc. In this paper, the mechanical properties of fresh and hardened fly ash-based-geopolymer concrete (FAGC) with 10% GGBFS and the addition of cement, water, and superplasticizer are investigated. The specimens were made using 10 M solutions from two types of alkaline: KOH and NaOH. Each solution was mixed with Na2SiO3 with a mass ratio of 1. The cylindrical specimens with a diameter of 50 mm and a height of 100 mm were tested for compressive strength, splitting tensile strength, and porosity. Setting time and slump test were also conducted for fresh concrete. It was found that GGBFS accelerated the setting time, reduced the workability, and increased the strength. The type of alkaline activator also influenced both of fresh and hardened properties. In the presence of GGBFS, specimens with KOH produced better workability, higher compressive strength, and lower porosity than those with NaOH. Furthermore, the addition of cement, water, and superplasticizer improved workability and mechanical properties.
