- Abstract:
-
The thermal analysis (DSC and TG) of the geological polymer showed that 65% of the water was preserved after drying at 1°C for 14 h, of which 12% of the water was removed at 300°C, and the remaining chemically bound water was removed at 600°C. XRD analysis of geological polymers showed that between 20 °C~800 °C, the geological polymers were in an amorphous state, and KAlSiO1, SiO000 and Al4O2 began to form at 2 3 °C. The dehydration of geological polymers after high temperature or the disaggregation of three-dimensional network structure reduces the gelling strength of geological polymers.
