Cement Production, Consumption Slightly Increase in 2011 According to an advance release of the U.S. Geological Sur‐ vey's 2011 Minerals Yearbook, production of portland and masonry cement in the United States increased by 2.2 per‐ cent in 2011 to a total of 67.9 million metric tons (Mt). Monthly production was erratic overall, showing year‐ over‐year gains of more than 10 percent in March, Novem‐ ber and December, but declines or essentially stagnant outputs in the other months. While the 2011 output is wel‐ comed as an improvement by the industry, it's the third lowest since 1992 and was 31.4 Mt less than the record output in 2005. As measured by sales to domestic final customers, U.S. con‐ sumption of cement increased by 2.6 percent to 72.3 Mt in 2011 after 5 years of consecutive declines; this was also the third lowest volume since 1992, and 55.7 Mt less than the record level in 2005. Only 16 states showed consumption declines of 1 percent or more in 2011; the largest decline was in Louisiana (down by 14.4 percent), which was likely due in part to severe rainfall from Tropical Storm Lee. Sev‐ eral states showed consumption gains of 10 percent or TXI Achieves Operational Status for New Kiln Texas Industries Inc. announced that the second kiln at its Hunter cement plant, near New Braunfels, Texas, has achieved operational status. Following a successful commis‐ sioning process which began in November 2012, the 1.4‐mil‐ lion‐ton kiln line has realized its design performance capabilities and is producing efficiently. The company also announced that it will accelerate mainte‐ nance and upgrade projects on the original production line, Kiln 1, to more quickly meet the growing needs of the market‐ place. Pending successful completion of plant maintenance and equipment upgrades, TXI expects to bring Kiln 1 back on‐ line during the first quarter of 2014. Combined with the newly added capacity of Kiln 2, the upgrades will enable TXI Hunter to efficiently produce and ship approximately 2.3 million tons of cement each year, more than double its original capability. "We initially projected a more extended period of downtime for the original line after Kiln 2 was brought into full opera‐ tional status. However, market conditions in central and south Texas continue to point to sustained recovery and strength, and we simply need the additional capacity earlier than originally thought," stated Jamie Rogers, TXI's vice presi‐ dent and CEO. "It is clear that TXI's mission to serve our cus‐ tomers is best met by utilizing all of our capacity in as swift a manner as feasible." more; the largest relative increases were in the District of Columbia, a 63 percent increase; and North Dakota, up by 46 percent. Although cement sales in 2011 rose only modestly, port‐ land cement sales for the fourth quarter were up by 7.5 percent and, together with increases in housing starts late in the year and other economic indicators of recovery, it was anticipated that cement sales might increase by as much as 10 percent in 2012. A return to consumption lev‐ els similar to the record years of 2005 and 2006 were not expected for at least another decade and only if the housing market and tax revenues to states (and hence public sector construction) recovered substantially. The report also stated that world production of cement in‐ creased 10.4 percent to 3.61 billion metric tons (Gt) in 2011. Given their recent rapid rise in production, Brazil, Iran, Russia, Turkey and Vietnam all appeared poised to possibly overtake the United States in cement output within the next five years.
