This research applied the bagasse ash which is a waste from the sugar mill industry to produce Geopolymer concrete. This type of concrete reduces the environmental effect. The bagasse ash was ground until the residual particle retained on sieve No. 325 less than 5percent. Two types of superplasticizers, namely, Type F and Type G were applied to the mixtures. The results of showed that the using of both superplasticizers improved the workability of Geopolymers concrete as increasing amount of usage. The superplasticizer Type G exhibited the highest workability. On the other hand, it was found that the compressive strength of geopolymer concrete decreased with higher workability. It was found that the using of superplasticizer at 1% was suitable for geopolymer concrete.
