Gates Foundation Headquarters' Green Design Includes Lafarge Slag Cement

Reston, VA

Lafarge North America Inc.


In pursuit of LEED® certification and other sustainable construction goals, new campus relies on NewCem® slag cement to achieve high-strength, long-term durability and resource conservation.


NewCem slag cement from Lafarge is making a strong contribution to achieving the sustainable construction goals of Seattle's newest landmark - the Bill & Melinda Gates Foundation headquarters. Located in the heart of the city near the famous Space Needle, the Gates Foundation campus sits on about 12 acres. When the 900,000-square foot complex is completed in the spring of 2011, it will include two six-story V-shaped office buildings with landscaped courtyards.


Even more impressive than the campus' size is the fact that its designers hope to earn a LEED Gold rating by the U.S. Green Building Council. This is one of the reasons why Seattle-based Stoneway Concrete selected Lafarge NewCem slag cement for the project.


NewCem is a high-performance, finely ground hydraulic cement produced from granulated blast furnace slag, a byproduct of the iron-making process. Using slag cement in concrete production consumes less energy than other cements and can be used to achieve LEED points. Engineered for long-term durability, NewCem slag cement helps achieve low permeability, increased resistance to chemical attack in concrete, greater strength potential, and improved workability.
