Effect of Different Molarity of Alkaline Activator on Fly Ash Based Concrete for Green Construction Materials (Without Cement)

Abstract

Geopolymer concrete is produced due to alkalination of substances rich in aluminium and silicon with an alkali solution, an aqueous solution of sodium hydroxide and sodium silicate. Alkali answer turned into various in special molar attention as eight M, 10 M, 12 M, and 14 M with hydroxide to silicate ratio of 2.5. Two one-of-a-kind set of concrete specimens have been casted which were viz. Fly ash primarily based handiest use in the geopolymer concrete. All the specimens had been cured at 60 °C in oven and elevated curing tank for twenty-four hours and atmospheric curing in lab till 7 days and 28th day. It became located that, oven dried curing confirmed a mild better strength than steam cured and it turned into a hit.
