Strength and workability of low lime fly-ash based geopolymer concrete


Geopolymer concrete prepared from low lime based fly-ash and a mixed alkali activator of sodium hydroxide and sodium silicate solution are investigated. An increase in compressive strength of these concrete samples is observed with increased molarity of NaOH solution. The workability of concrete decreases when the molarity of NaOH solution is increased for the samples cured at 60o C.
Keywords: Concrete, fly-ash, geopolymer, compressive strength.
