The performance of the geopolymer was investigated on the basis of compressive strengthSEM along with EDS. Pure sodium hydroxide specimens displayed decreased strength. However the combination of sodium hydroxide and sodium silicate specimen with aSi/Al ratio of 2 showed maximum strength, whereas the specimen after Si/Al ratio 2 showed decrease in strength. © (2015) Trans Tech Publications, Switzerland. %K Aluminum alloys; Coatings; Compressive strength; Fly ash; Geopolymers; Silica; Silicates; Sodium hydroxide, Coating application; Geopolymer; Maximum strength; Si/Al ratio; Sodium silicate; Solid-to-water ratio, Inorganic polymers %P 355-361 %A A.
