Geopolymer is a supplementary potential binder to Portland cement. The production of geopolymer concrete can be done by using supplementary cementitious alternatives like silica fume, flyash, rice husk ash, ground granulated blast furnace slag (GGBS), etc., Self compacting geopolymer concrete (SCGC) can be considered as an appreciable and inventive construction material and can be noticed as a revolutionary development in the field of concrete technology. It is an innovative type of concrete that can achieve the combined advantages of both geopolymer concrete (GPC) and self compacting concrete (SCC). As the name implies, it does not need any compacting efforts to achieve full compaction and SCGC that is produced by a polymeric reaction of alkaline activator solution with a SCM’s as a binder for matrix formation and strength.
In the present investigations, low calcium flyash based GPC replaced with GGBS in 20%, 40%, 60%, 80%, 100% proportions. The concrete specimens those are cured in oven curing as well as cured in ambient temperature will be investigated experimentally under different tests. The workability, mechanical& durability characteristics are studied for different mix replacements. The conclusions shown that the incorporation of GGBS in flyash based SCGC, accordingly it enhances the hardened properties in early age. The workability characteristics are decreased by the addition of GGBS with flyash as replacement & also the compressive strength increases with increase of binder content. The durability characteristics also shown that the SCGC specimens are more durable compared to specimens that are replaced when GGBS replaced with flyash.
