Abstract – Continuous increase in production of cement causes large amount of carbon-dioxide emission which results in greenhouse effects. In order to overcome this problem many researchers have put in their efforts to achieve optimum strength of concrete by replacing cement with fly ash and when it combine with alkaline solution emerge to a new technology called as Geo polymer concrete. Self compacting geo polymer concrete (SCGC) is an improved way of concreting execution that does not require compaction and is made by complete elimination of ordinary Portland cement content. SCGC is synthesized from low calcium fly ash, activated by combination of sodium hydroxide and sodium silicate solution and by incorporation of super plasticizer for self-compatibility. This study is an attempt to observe strength characteristics of SCGC by suitable selection of super plasticizers available in market and testing their viability on SCGC. The fresh properties for morality of 8M, 10M, 12M, 14M, and 16M of SCGC were assessed through T 50 Slump test, slump flow, L-box and U-box test methods. Strength tests such as cube compressive strength, splitting tensile test for cylinder, beam flexure was also tested for the period of 7 and 28 days in the heat curing method. Finally flexural response is also studied to analyze the stress variation taking place in SCGC beam.
