Cement Setting and Strength Formation

Cement setting and strength formation begin when water is added to cement particles. The main reaction is called hydration. During hydration, the anhydrous cement compounds react with water and form new solids that help harden the material.

Hydration can happen by two main paths: through-solution...

Hydration of cement begins when water is added to cement particles.

In the presence of water, the anhydrous cement compounds initially dissociate, releasing ions into the water that eventually form hydrates of silicates and aluminates in the solution and get precipitated, holding the cement grains in position.

Subsequent hydration ...
