A Scientometric Review of Na2SiO3/NaOH Versus SiO2/Na2O is above 2.85:1 Alkaline solution Activated Geopolymer Concrete

The term geopolymer is a sustainable binder refers to the study of waste materials 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 quality 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 documented 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 degrees Celsius 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 analyzed difference between the Na2SiO3/NaOH activated geopolymer concrete versus neutral grade sodium silicate (NGSS) laboratory-based field construction geopolymer concrete. NGSS is a neutral grade of SiO2: Na2O. This solution is the only single neutral grade solution with 2.92 silica modulus, produced directly by the company to create the geopolymer.
