The term geopolymer is a sustainable binder refers to the study of waste mate- rials containing silicon (Si) and aluminum (Al), which create an alternative binder formed by a complex repeated chain by geopolymerization process. Hellacious materials alternation is mandatory to see the construction as a beautiful infrastructure as there are limited natural resources to produce qual- ity concrete. Alternative binder and aggregates created by using industrial waste should be used to reduce the disadvantages of conventional concrete. The Na2SiO3 / NaOH ratio activated geopolymer concrete has been well doc- umented by researchers. The ratio of these solutions to the field geopolymer concrete production is not suitable for structural geopolymer concrete because it is not possible to provide a temperature greater than 60 degree centrigrade in the field. The Na2SiO3 / NaOH ratio should be mixed 24 hours before airing the samples. Researchers have used a single alkaline solution simply instead of water when mixing concrete. In this review paper clearly compared and ana- lyzed difference between the Na2SiO3/NaOH activated geopolymer concrete versus neutral grade sodium silicate (NGSS) laboratory-based field construc- tion geopolymer concrete. NGSS is a neutral grade of SiO2: Na2O. This solu- tion is the only single neutral grade solution with 2.92 silica modulus, produced directly by the company to create the geopolymer.
