Aggregates Production Rises in Second Quarter According to USGS, an estimated 546 Mt of total construction aggre‐ gates was produced and shipped for consumption in the United States in the second quarter of 2012, an in‐ crease of 3.4 percent compared with that of the second quarter of 2011. The estimated production for consumption in the first 6 months of 2012 was 898 Mt, an increase of 5.6 percent compared with that of the same period of 2011. The estimated production‐for‐con‐ sumption of construction aggre‐ gates in the second quarter of 2012 increased in four of the nine geo‐ graphic divisions compared with that sold or used in the second quarter of 2011. The largest in‐ creases in percentages were recorded in the West North Central and East North Central divisions. Production‐for‐consumption in‐ creased in 28 of the 45 states that were estimated. The five leading states, in descending order of pro‐ duction‐for‐consumption, were Texas, California, Pennsylvania, Ohio and Missouri. Their combined total production‐for‐consumption was 169 Mt and represented 31 percent of the U.S. total. An estimated 316 million metric tons (Mt) of crushed stone was pro‐ duced and shipped for consumption in the United States in the second quarter of 2012, a slight increase compared with that of the second quarter of 2011. The estimated pro‐ duction‐for‐consumption in the first 6 months of 2012 was 532 Mt, an in‐ crease of 4.3 percent compared with that of the same period of 2011. The estimated production‐for‐con‐ sumption of crushed stone in the second quarter of 2012 increased in three of the nine geographic di‐ visions compared with that sold or used in the second quarter of 2011. The increases were recorded in the East North Central, West North Central, and West South Central divisions. Production‐for‐consumption in‐ creased in 24 of the 46 states that were estimated. The five leading states, in descending order of pro‐ duction‐for‐consumption, were Texas, Pennsylvania, Missouri, Ohio and Virginia. Their combined total production‐for‐consumption was 112 Mt and represented 36 percent of the U.S. total. The estimated U.S. output of con‐ struction sand and gravel pro‐ duced and shipped for consumption in the second quarter of 2012 was 230 Mt, an increase of 6.5 percent compared with that of the second quarter of 2011. The estimated production‐for‐con‐ sumption in the first 6 months of 2012 was 366 Mt, an increase of 7.4 percent compared with that of the same period of 2011. The estimated production‐for‐con‐ sumption of construction sand and gravel in the second quarter of 2012 increased in seven of the nine geographic divisions com‐ pared with that sold or used in the second quarter of 2011. The largest increases in percentages were recorded in the West North Central, New England, and East North Central divisions. The estimated production for consumption in the first 6 months of 2012 was 898 Mt, an increase of 5.6 percent compared with that of the same period of 2011. www.rockproducts.com Stone-Producing States AGGREGATES The five leading states, in descending order of produc- tion-for-consumption, were Texas, California, Pennsylva- nia, Ohio and Missouri.

The estimated portland cement consumption increased by 12 per‐ cent in the second quarter of 2012 compared with that of the second quarter of 2011. The estimated consumption in the first 6 months of 2012 increased by 15 percent compared with that of the same pe‐ riod of 2011.
