Lafarge Blended Cements provide a significant contribution to sustainable construction. The use of these materials in concrete production consumes less energy and offers improved efficiency and building performance. These materials can also be used to help achieve LEED (Leadership in Energy and Environmental Design) points in the USGBC's (U.S. Green Building Council) and CaGBC’s (Canada LEED programs. The 12.9 km (8 miles) long Confederation Bridge connects Prince Edward Island with New Brunswick in Eastern Canada. The main structural elements, consisting of piers and girders, were precast...
