摘要：
Increase in the dosage of superplasticizer can have a significant effect on workability and strength properties of Geopolymer concrete in ambient curing. This paper evaluates the influence of different superplasticizer doage on workability and strength properties of GGBS based Geopolymer concrete. In this study, Geopolymer concrete was made up of 100% GGBS, sodium silicate to sodium hydroxide ratio of 2.5, Alkaline to Binder ratio of 0.5, superplasticizer (2% to 6%) and the concentration of sodium hydroxide of 12M. Significant increase in workability and slight decrease in strength was observed with increase in superplasticizer under ambient curing. The combination of 6% superplasticizer and 12M NaOH concentration of GGBS based Geopolymer concrete was advisable for precast construction under ambient curing. (C) 2019 Elsevier Ltd.
