process of cement

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.
