Geopolymerization of MKG

The geopolymerization process is a key influencing factor of the mechanical properties of materials and chemical durability of geopolymers. In this chapter, vacuum dehydration and nuclear magnetic resonance analysis were conducted to investigate the geopolymerization process of fresh MKG paste. Four distinct stages of geopolymerization were identified, including dissolution, short-ranged polymerization, structural rearrangement, and long-ranged condensation. Every stage was characterized by its reaction duration and Qm(nAl) evolution. The findings from this study offer new insights into the mechanism through which the loss of free water affects the structural rearrangement of geopolymers.
