Alkali activated concrete (AAC), gained significant attention by researchers, educators and construction practitioners during past decades. Due to its rapid strength gain and better mechanical properties it proved better alternative to cement concrete. However, its field application is still limited due poor workability and lack of data. Moreover traditional AAC required an elevated curing, which again was a major drawback for in situ construction. Many researchers have tried to eliminate this drawback by using different pozzolanic binders and came up with the AAC that doesn’t required any heat curing. This research paper represents strength parameter of AAC cured at ambient temperature and tested at the age of seven days for compressive strength test, splitting tensile strength test and flexural strength test. Three different pozzolanic binder Fly ash (FA), Ground granulated blast furnace slag (GGBFS) and silica fume (SF) have been used to prepare ambient cured AAC.
