Dicalcium silicate → Calcium hydroxidea, monohydrate

Participants

Reaction Steps

Calcium silicate in cement and the calcium hydroxide source material added cause, by hydration, calcium silicate hydrate and calcium hydroxide crystals, respectively, to precipitate out. By carrying out a grinding operation on that occasion simultaneously with the hydration reaction, the crystal growth of hydration reaction products is suppressed by the impact and friction between grinding media (milling balls etc.) and the materials to be ground (hydration reaction products) and, as a result, very fine calcium silicate hydrate particles and calcium hydroxide hydrate particles are formed.
