Aggregates Production Up Slightly in 2012


USGS just reported full-year 2012 production numbers, and aggregates production has taken a step forward. The estimated annual output of construction aggregates produced for consumption in 2012 was 1.99 billion metric tons (Gt), a slight increase compared with that of 2011's total of 1.93 Gt. An estimated 484 million metric tons (Mt) of total construction aggregates was produced and shipped for consumption in the United States in the fourth quarter of 2012, a slight decrease compared with that of the same period of 2011.

Of the 2012 total, the estimated annual output of crushed stone produced for consumption was 1.16 Gt, a slight increase compared with that of 2011. An estimated 282 Mt of crushed stone was produced and shipped for consumption in the United States in the fourth quarter of 2012, a slight decrease compared with that of the same period of 2011.

Of the 2012 total, the estimated annual output of construction sand and gravel produced for consumption was 823 Mt, a slight increase compared with that of 2011. The estimated U.S. output of construction sand and gravel produced and shipped for consumption in the fourth quarter of 2012 was 202 Mt, a slight increase compared with that of the same period of 2011.

Shipments of portland cement increased by an estimated 9 percent in the fourth quarter of 2012, and annual consumption increased by an estimated 10 percent in 2012, compared with consumption in 2011. This information is obtained from the USGS monthly survey of U.S. cement producers.

The estimated production for consumption of construction aggregates in the fourth quarter of 2012 increased in three of the nine geographic divisions compared with that sold or used in the fourth quarter of 2011. In the fourth quarter, production for consumption of aggregates increased in 18 of the 43 States for which estimates were made. The estimated total annual production for consumption of construction aggregates in 2012 increased, compared with that of 2011, in 31 of the 50 States for which estimates were made.

The five leading States, in descending order of total annual output for 2012, were Texas, California, Pennsylvania, Ohio and Missouri. Their combined total annual output was 588 Mt, an estimated increase of a little greater than 5 percent when compared with that of 2011.

The estimated production for consumption of crushed stone in the fourth quarter of 2012 increased in four of the nine geographic divisions compared with that sold or used in the fourth quarter of 2011. Production for consumption of crushed stone increased in 20 of the 43 States for which estimates were made. The five leading States, in descending order of production for consumption, were Texas, Pennsylvania, Missouri, Florida and Illinois. Their combined total production for consumption was 96.8 Mt and represented 34 percent of the U.S. total.

The estimated production for consumption of construction sand and gravel in the fourth quarter of 2012 increased from fourth quarter 2011 levels in three of the nine geographic divisions. Production for consumption of construction sand and gravel increased in 20 of the 46 States for which estimates were made. The five leading States, in descending order of production for consumption, were Texas, California, Arizona, Michigan and Colorado. Their combined total production for consumption was 63.9 Mt and represented 32 percent of the U.S. total.
