The Preparation of C-S-H Powder Seeds and Their Effect on the Early Hydration Performance of Cement Paste by Chunlong Huang, Yiren Wang, Zhongyuan Wei, Yong Yu

“…The hydration kinetics showed that the hydration of cement mixed with nucleating agents was not governed by a single reaction mechanism, but rather constitutes a complex, multi-component reaction process. As the content of nucleating agents increased, higher dosages of nucleating agents accelerated the production of more products within a short period, causing the system to rapidly transition to phase boundary reaction control. …”
