Based on mixing composition, curing conditions, geopolymer shows different performance. The most important parameter in consideration with the synthesis of geopolymer is curing condition. In this research, a relative study between the requirement of curing temperature and curing time with the mix combination was studied. Three series of samples were separated into different curing condition such as curing at 35 o C, 55 o C, 85 o C for 1 day and up to 2 days. The workability at green state and compressive strength at harden sate were evaluated. Result showed that curing condition has been significantly influenced on the mixing composition. The change in strength with the increase in curing temperature is remarkable for fly ash based geopolymer without any calcium compound as a supplement. Whereas geopolymer specimens blended with calcium compound led to optimized strength even at lower curing temperature. Similarly curing at higher temperature for prolong period is not necessarily required for the sample containing calcium compound as a supplementary material.
