Fall in US construction materials production levels

The USGS has released its mine and plant production data for selected mineral commodities for the first quarter of 2014 (ended 31 March).

Domestic production levels for construction materials (cement, construction sand and gravel, crushed stone and gypsum) decreased substantially in the first quarter of 2014 compared with levels in the fourth quarter of 2013 due to seasonal fluctuations that were influenced by weather conditions. The decreases were typical of those seen during the first quarter of most years. Production for these mineral commodities in the first quarter was about 4% greater than during the first quarter of 2013.

• US production of cement saw a slight increase from 14 million t in 1Q13 to 14.5 million in 1Q14 but a decrease from 18.8 million t in 4Q13.
• Production of gypsum also witnessed a marginal increase from 2.9 million t in 1Q13 to 3 million t in 1Q14; however, production levels fell from 4 million t in 4Q13.
• Construction sand and gravel production rose from 135 million t in 1Q13 to 141 million t in 1Q14 and decreased from 212 million t in 4Q13.
