Hydration Accelerating Effect and Strength Characteristics of Mixed Cement by C-S-H Based Hydration Core

Nucleaion effect, Calcium silicate hydrate, Blast furnace slag, Fly ash, Mixed cement

When an admixture such as blast furnace slag and fly ash used as a substitute for cement is used, there is a problem in that initial hydration and strength are lowered. In this study, it was concluded that the problem of hydration and strength degradation could be improved using C-S-H (Calcium silicate hydrate) nucleation seeding, which plays a core role in cement hydrate formation, and the resulting hydration performance and strength characteristics could be analyzed to compensate for the shortcomings of mixed cement
