Cement Hydration at Room Temperature

After mixing cement with water, the liquid phase is quickly saturated with calcium and S04 ions the pH value grows to attain the level close to 12.5. The sodium and potassium ions are quickly released to the solution the maximum of their concentration is observed after 1 day of hardening and it becomes unchanged within [Pg.205]

28 days [4]. The Na+ and K+ ions shift the equilibrium in the liquid phase to the left side  [Pg.206]

Consequently, the lowering of calcinm hydroxide solubility together with the increase of gypsum solubility is observed [1, 5, 6], [Pg.206]
