The hydration of cement is not a sudden process. This reaction is faster in early period and continues indefinitely at a decreasing rate. What Happens During Hydration of Cement During hydration of cement, C3S and C2S react with water and calcium silie hydrate (CSH) is formed along with calcium hydroxide Ca(OH)2.

Hydration of the cement, the major Bouges compounds C 3 S and C 2 S are responsible for the setting and the hardening of the cement. In the presence of water, the silies and aluminates form products of hydration that will result in a hard mass over a period of time. This hard mass is called as the Hydrated Cement Paste (HCP).

[7] Conclusion This paper investigates the effect of silica fume and polycarboxylic ether based superplasticizer on the hydration process of commercial Portland cement. Without superplasticizer, the quantities of Ca(OH)2 after 1 day of hydration of silica fume blended cement paste are lower than for pure cement paste, thus indiing pozzolanic reactivity of silica fume with Ca(OH)2.
