Binder-Scale Creep Behavior of Metakaolin-Based Geopolymer
In this study, the creep behavior of binder phase in metakaolin-based geopolymers (MKGs) was investigated using nanoindentation. The underlying influence of the Si/Al ratio on the creep behavior was determined from detailed microstructure characterization and micromechanical analysis. The results indicated a strong correlation between the binder-scale creep behavior in MKG and its microstructure, particularly the characteristic pore size, which was further related to the Si/Al ratios of the binder. Combined with micromechanical analysis, the underlying influence of the composition and structure on the creep behavior in MKG was further explained.
