Cement process

Jun 09, 2021

Nov 15, 2020 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
