· Ca3Si2O7

Ca3Si2O7 is a calcium silicate ceramic compound belonging to the silicate family, commonly known as dicalcium silicate or a component of Portland cement clinker phases. This material is primarily encountered in civil construction as a constituent of cement and concrete systems, where it contributes to early-stage strength development and hydration reactions. Its significance lies in its role as a binding phase in cementitious materials; engineers select cement formulations partly based on their content of calcium silicates like this compound to control setting time, heat of hydration, and long-term durability in structural applications.
