Dicalcium Silicate is about (25 – 40 %) of cement. It hydrates and hardens slowly and takes a long time to add to the strength (after a year or more). It imparts resistance to chemical attack.
Dicalcium silicate (C2S) in cement contributes to long-term strength development and durability. It reacts more slowly with water compared to tricalcium silicate (C3S), providing strength over time and generating less heat during hydration.
