The most common chemical constituents used to classify Portland cement are C 3 A (tricalcium aluminate), C 3 S (tricalcium silicate), C 4 AF (tetracalcium aluminoferrite), and a concept called the ‘heat of hydration’. Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration.
