Abstract: This paper illustrates the posterior results of the experiments that are done to testify the functionality of Ground Granulated Blast-furnace Slag (GGBS) as a replacement of workability, time set, and compressive force features of geopolymer concrete fly ash precast elements treated by ambient temperature.The rapid setting is a common disorder characterized by difficulty of the casting of the geopolymer concrete fly ash which needs materials to be added to limit the rapid setting and enhance the properties. Therefore, the curing process of the geopolymer concrete fly ash must be determined to decrease the growth of cracking resulting from the hydration of the mix.Three mixes were examined with various ratios of GGBS (10%, 30%, 50%) and the one mix without any replacement is contained 100% fly ash as a control mix.Throughout a rational mix,the design was occupied to get an optimum the optimum mix proportions, the alkaline Alkali, which is a solution that is utilized for the sake of this study, and it consists of sodium hydroxide sodium and silica fume solution were added to the binder at a concentration of 25%.Tests were executed on the following three dimensions: 100x, 100x , and 100mm cube Geopolymer mortar samples.Two fly ash types are used in this study, and they are class C and class F, and they were examined via Energy Dispersive X-ray (EDX) and scanning electron microscope (SEM) in order to preserve their phases. The incorporation of GGBS with Class F fly ash helped in reaching achievable time setting and compressive strength for precast elements in comparison to those of class C Fly ash geopolymer concrete. Another substantial finding was achievingground highly amount of GGBS on fly ash geopolymers, and it is appropriate for restoration without the presence of high heat.
