Slag-based geopolymer is a new material, and it is necessary to study its adaptability with superplasticizer to assure its engineering applications. Different modules of water glass were used to activate slagbased geopolymer which was prepared by powder of slag and metakaoline. Fluidity of slag-based geopolymer paste and the optimum content of superplasticizer in slag-based geopolymer mortar were used as evaluation standard in order to study the adaptablity of slag-based geopolymer with superplasticizer. In the study, it appears that the saturated content of naphthalene superplasticizer is 2.0 %, and the optimum content is 0.6 % ; the saturated content of melamine superplasticizer is 2.3 %, and optimum content is 1.6 %. The results show that the adaptability of naphthalene superplasticizer and melamine superplasticizer with slag-based geopolymer is perfect which performed as obvious saturated point and optimum content.
