2CaOSiO2
2CaO·SiO2, commonly written as 2CaO·SiO2 or Ca2SiO4, is known in chemistry as dicalcium silicate and is a key calcium silicate phase. In cement science it is more widely referred to as belite (C2S). Belite is one of the principal mineral components in ordinary Portland cement clinker, typically forming alongside alite (Ca3SiO5) during high-temperature kiln processing.
In natural form, Ca2SiO4 exists as a mineral belite, which shows several polymorphs that depend on temperature
Hydration and properties are central to belite’s role in cement. When cement hydrates, belite reacts with water
Applications and significance center on cement climatology and performance. Belite-rich clinkers yield low-heat cement, useful for
