Sprint Nextel Corporation (NYSE: S) is a telecommunications company based in Overland Park, Kansas. The company owns and operates Sprint, the third largest wireless telecommunications network in the United States, with 49.9 million customers, behind Verizon Wireless and AT&T Mobility.
Sprint is a global Internet carrier and makes up a portion of the Internet backbone. In the United States, the company is the third largest long distance provider and also owns a majority of Clearwire, which operates the largest wireless broadband network.
The company was renamed in 2005 with the purchase of Nextel Communications by Sprint Corporation. The company continues to operate using two separate wireless network technologies, CDMA and iDEN (for Nextel and some Boost Mobile subscribers). In 2006, the company spun off its local landline telephone business, naming it Embarq (which was subsequently acquired by CenturyTel). In 2009, Sprint reached an agreement to outsource management of its wireless networks to Ericsson.
Sprint Nextel launched its first WiMAX wireless card on December 21, 2008 (The Franklin Wireless u300 broadband card), and the first WiMAX phone available in the United States (The HTC Evo 4G) on June 4, 2010, utilizing its WiMAX technology from Clearwire Corp. A recent Consumer Reports survey tied Sprint with perennial front-runner Verizon Wireless in terms of customer satisfaction, a big improvement over previous years.[2]
Recently, in 1998, U.S. imports of cement satisfied 23 percent of U.S. consumption as measured by volume, up from 18 percent the previous year, and in 1999 imports accounted for 27 percent of consumption. This compares to similar peaks in 1987 and 1988, when U.S. demand was strong and imports were abundant, and contrasts with the 8 to 9 percent levels in 1992 and 1993, when the U.S. construction sector was recovering from a recession. Imports are likely to continue to increase through 2004, although at diminishing levels. The United States has little cement available for export. Exports account for about 1 percent of U.S. production, and most are sent to Canada.

Industry Definitions
Portland cement: cement useful to make concrete, it is made up of grout, concrete and mortar.
Pozzolan-lime cements: cement mixture preferred for its strength.
Slag-lime cements: activated by the addition of alkalis into the cement.
Supersulfated cements: contains 80% ground granulated blast furnace slag, 15% gypsum or anhydrite and a little Portland clinker or lime as an activator. This cement is used to make structures exposed to sulfates.

Trends and Recent Developments
The capacity for cement production is expanding worldwide, including in the United States. Despite the enormous cost associated with building a new plant (capital outlay and energy costs), strong domestic demand justifies the expansion. New plants can cost as much as $300 million, and major modernization and expansion can cost more than $50 million. Most capital expenditures in the late 1980s and early 1990s were for replacement equipment (kilns, crushers, mixers, etc.), to meet environmental requirements, and for energy conservation projects. No new plants were built in that period, largely because of the high capital financial status of the producers. Starting in the second half of the 1990s, however, the number of major modernizations increased, and a few new plants are being built or are in the planning process.
