hydration of cement

-when water is added to cement , ph value rises , temperature rises
-c3s and c2s react with water to set and harden
-c3s mainly responsible for hydration

hydration process
2c2s +4H - C3S2H3 + Ca (OH ) 2
(calcium silicate hydrate ) (calcium hydroxide )


2c3s+ 6H - c3s2 H3 + 3Ca(OH )2
