Nucleation seeding in cementitious systems

Influence of C-S-H-nuclei on Portland cement hydration rate has been investigated. C-S-H-seeds were prepared by mechanochemical synthesis and by sol-gel processes. The specific surface area of C-S-H-seeds has a major impact on the ability of the seeds to accelerate cement hydration. The larger the surface area is the more efficient is the acceleration.
