Tricalcium Silicate

Portland cement is produced from clinker by grinding with approximately 5 per cent natural gypsum (usually composed of a mixture of calcium sulfate dihydrate, CaSO 4 ·2H 2 O, and anhydrite, CaSO 4), in order to regulate the setting time of the cement. Portland cement is ground until more than 90 per cent passes through a 90 μm sieve.
