This paper reports the results of an experimental work
conducted to investigate the effect of curing conditions on the
compressive strength of selfcompacting geopolymer concrete
prepared by using fly ash as base material and combination of sodium
hydroxide and sodium silicate as alkaline activator. The experiments
were conducted by varying the curing time and curing temperature in
the range of 2496 hours and 6090°C respectively. The essential
workability properties of freshly prepared Selfcompacting
Geopolymer concrete such as filling ability, passing ability and
segregation resistance were evaluated by using Slump flow,
Vfunnel, Lbox and Jring test methods. The fundamental
requirements of high flowability and resistance to segregation as
specified by guidelines on Selfcompacting Concrete by EFNARC
were satisfied. Test results indicate that longer curing time and curing
the concrete specimens at higher temperatures result in higher
compressive strength. There was increase in compressive strength
with the increase in curing time; however increase in compressive
strength after 48 hours was not significant. Concrete specimens cured
at 70°C produced the highest compressive strength as compared to
specimens cured at 60°C, 80°C and 90°C.
