located in geopolymer concretes, with a huge quantity of GGBFS and less SS to SH ratio within the combinations [11]. Geopolymer Concrete is an alternative material to OPC, but due to its viscosity nature, the problem causes in compaction. To overcome the issue, Self Compacting Geopolymer Concrete has been introduced.
Currently, geopolymer gain new interest to treat wastewater and replacing the conventional adsorbent use which normally used in the production of cement. First identification of geopolymeric materials as an alternative to conventional Portland cement and concrete composites in 1979 [7]. Geopolymer can be viewed as an economic zeolite
