Effect of molarity of sodium hydroxide and molar ratio of alkaline activator solution on the strength development of geopolymer concrete

In the current study, effect of SiO 2 /Na O ratio in Sodium silicate (Na 3 ) solution, Na /NaOH and molarity NaOH on compressive strength geopolymer concrete. A mix design is formulated with various mixes are casted alkali activator solution (AAS) / fly ash (FA) =0.5 constant content. The molar altered from 1.50 to 3.00 for different ratios (2.0, 2.5 3.0) also molarities (8M,10M,12M,14M,16M 18M) studied their synergic Results highlighted that 16M yields high when around 2.00 2.40 /NaOH=2.5.
