What are the 5 Stages of Cement Hydration Process - Civil
2020-11-15 · The cement hydration process is not instantaneous. The reaction is faster in the early stages and continues indefinitely at a reduced rate. 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 ...
