What are the 5 Stages of Cement Hydration Process
Unless the cement is very finely ground and reground with excess water to regularly expose a fresh surface, it cannot be fully hydrated in a year or more. We can divide the process of hydration of cement into 5 phases, initial mixing reaction. Dormancy. Strength acceleration. Speed Reduction. Steady development.
