The emission of Carbon dioxide is no exception in the construction industry, but rather extensive. Establishing an alternative Cementing material adds an advantage in addressing the subject. As part of this, attempts to produce Cement through the activation of alkalis, which is both eco-friendly, and viable is the major add-on. Through the literature available, it is evident that the preparation of Alkali Cement is advantageous in all aspects, but the best suitable combination of chemicals is still the concern. Moreover, there are not many conclusions stated regarding the storage period or the service life of the attained Alkali Cements. Thus, this study aims to determine the storage period of the Alkali/ Green Cements produced through the alkaline medium created using Sodium Silicate and Magnesium Oxide (Na2SiO3&MgO), while disentangling the role of MgO. Three different weight combinations of Na2SiO3 and MgO were ventured, using Fly Ash (FA) and Ground Granulated Blast Furnace Slag (GGBS) by fixing the GGBS content to 30%. X-Ray Fluorescence (XRF) and Heat of hydration (HOH) were adopted to understand the performance variation of the Cement because of the age. Whereas Fineness by Blaine’s Permeability, Soundness, Standard Consistency, Initial & Final Setting time (IST & FST), Compressive strength, and Density were conducted along with XRF and HOH to derive the ideal mix case. Further, it is undeniable that the use of MgO in just the right amount can help enhance performance in terms of strength and shrinkage. Out of the combination of Alkalis used, the optimum percent of MgO is found out to be 10% when combined with 10% of Na2SiO3. A compressive strength of 33MPa was attained, by mere ambient curing. Through the study, it is observed that Alkali Cement has a minimum service life of 1 month.
