Ca₂SiO₄ (dicalcium silicate) is an inorganic ceramic compound and a primary constituent phase of Portland cement clinker. It is a brittle, refractory ceramic material that forms during high-temperature calcination of limestone and silica-bearing materials. This material is notable for its role in cement hydration and strength development, making it fundamental to concrete and masonry construction worldwide, where its reactions with water over time provide long-term durability and load-bearing capacity that alternatives like pure calcium carbonate cannot match.
