Cement Production in the US

The cement manufacturing sector remains a vital industry in the U.S. and throughout the world. After China and India, the U.S. is the world's third largest cement producer. Portland cement is a $13 billion industry in the U.S. [12]. In 2005, the U.S. consumed a record 127 million metric tons (140 million short tons) of Portland cement [13] and the U.S. Portland cement industry produced approximately 104 million short tons (94 million metric tons) of cement [14].

In 2005, Portland cement was produced at 115 plants located in 37 States and Puerto Rico. The U.S. cement manufacturing sector is concentrated among a relatively small number of companies. Many U.S. cement plants are owned by, or are subsidiaries of, foreign companies [14]. Together, 10 companies accounted for about 80% of the total U.S. cement production in 2005 [15]. California, Texas, Pennsylvania, Florida, and Alabama are the five leading cement-producing states and accounted for about 48% of the total U.S. production in 2005 [15].
