This paper discusses alkali-activated material focusing on low calcium fly ash. The preliminary work investigated setting time and compressive strength of alkali-activated paste using two different of low calcium fly ash, one from the Power Plant in Japan, the other from a fertilizer plant in Indonesia, respectively denoted JFA and IFA. The paste which was consolidated using ash required the final setting times: JFA-ash paste - 4.5 - 7 days; IFA-ash paste - 1.5 - 2 days. This subsequent investigation applied incorporation of ground granulated blast furnace slag (GGBFS) and micro-silica (M) as JFA-ash replacement in Alkali-activated Mortar (AAM) to enhance system performance. The work reveals effects of GGBFS and M incorporated to JFA-ash mixed alkaline solution on flowability, compression, flexural strength, drying shrinkage, microstructure and Interfacial Transition Zone (ITZ) performance.
