Cement Products | Construction Materials - CEMEX USA

Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement. Cement is the most widely used construction material worldwide.
