After 20 years, C–S–H, portlandite, AFm, HTlp, ettringite and carbonate existed.
- •
Increasing GGBS enhances incorporation of H+ and AlO45− into C–S–H structures.
- •
Chain growth is proportional to GGBS contents, enhanced by high temperatures.
- •
CH functions as “a catalyst” in the process of pozzolanic reaction of GGBS.
