abstract = {This Research Work Aimed to Investigate the Fresh Properties, mechanical Properties, and Durability Properties of Fly Ash Based Self Compacting Geopolymer Concrete with Silica Fume as a Partial Replacement to Fly Ash by 0%, 2.5%, 5%, 7.5% &10% with constant GGBS content. Grade of concrete used in this research is M30. In this study, evaluate the effect of Silica fume, powder content, and PCE Superplasticizer on self-compacting geopolymer concrete. Five concrete mixes (SCGC-F65-G35-S0, SCGC-F62.5-G35-S2.5, SCGC-F60-G35-S5, SCGC-F57.5-G35-S7.5, and SCGC-F55-G35-S10) were made by replacing fly ash with silica fume. The 12 M molarity of sodium hydroxide is used for all the mixes. Alkaline liquid to binder by mass is 0.43. The binder content can be further divided into fly ash and GGBFS. The fly ash content is on the higher side, the fly ash content is taken as 65% and the GGBFS is taken as 35%. Super plasticizer PCE of 6% is added to all the mixes to enhance the properties of concrete. Fresh properties of concrete mix were measured by slump flow test, T50cm slump flow, L-box test and U-box test and harden properties are measured by compressive strength, split tensile strength and flexural strength and NDT-test for concrete like UPV and rebound hammer test were done. The workability of self-compacting geopolymer concrete has been decreased in addition of silica fume with a partial replacement to fly ash by 2.5%, 5%, 7.5% & 10%. The compressive strength, splitting tensile strength and flexural strength for 0% replacement of silica fume with fly ash (SCGC-F65-G35-S0) at 7, 14 and 28 days was found higher strength than other mixes.},
