Summary, etc. This study involves the application of replacement material to cement which eliminates the carbon-dioxide emissions.Cement production industries alone give out 5 to 8 % of greenhouse gas into the atmosphere globally. Naturally,geopolymer concrete emits very low greenhouse gas compared to ordinary portland cement (OPC). Therefore, geopolymerconcrete is greatly ecological and alternative material for OPC. This research has been intended to study the impact onworkability and mechanical properties of fly ash based geopolymer concrete using ground granulated blast furnace slag(GGBFS) along with manufactured sand (M-Sand) under ambient curing condition. The work has been executed to explorecompressive strength of G30 grade geopolymer concrete along with split tensile, flexural strength and its workability. Theresult shows that there has been increased strength and decreased workability with higher GGBFS &amp; M-sand. Further, itshows the optimum percentage replacement of 20% of GGBFS &amp; 50% of M-sand has been yielded G30 grade geopolymerconcrete easily. Based on the investigation, better strength has been achieved by full replacement of natural sand withM-sand. Statistical analysis such as simple linear &amp; multi variables regression has been carried out and formulas have beenanticipated to find relationship between the mechanical properties of geopolymer concrete while increasing percentage ofGGBFS.
