Experimental studies of Ambient Cured Geopolymer Concrete

Abstract

The objectives of the present work is to finalize the parameters such as Amount of binder used, Molarity of NaOH, Ratio of Na 2 SiO 3 /NaOH and Ratio of Liquid to Binder In the présent work, experimental investigations were performed such as compressive strength test on the ambient cured geopolymer concrete. By trial casting geopolymer concrete paramètres were finalized such as binder (Fly Ash : GGBS)as (40 :60), molarity content as 8M, Ratio of Na 2 SiO 3 /NaOH of 1.5 and Ratio of Liquid to binder of 0.5.. The tests were conducted for Geopolymer Concrete spécimens at diffèrent curing âges of (1, 3 and 7 days). The results of compressive strength of Binder ratio of (fly ash : GGBS) of (40 :60), Molarity of NaOH of 8M ,Ratio of Na 2 SiO 3 /NaOH of 1.5 and Ratio of Liquid to binder of,0.5 gave a higher results of 24 N/mm 2 ,40 N/mm 2 60 N/mm 2 for 1,3 and 7 days respectively.
