December 28, 2007—One of the biggest breakthroughs in construction technology—the innovative iCRETE system, offering record strength concrete and dramatic environmental benefits is being used to build the Freedom Tower at Ground Zero in New York City, says the comapny. Both the 1,776 foot-tower, as well as the 186-foot inner safety core supporting the superstructure, will be built with iCRETE.
“The world is watching as we build the Freedom Tower,” stated Daniel R. Tishman chairman and chief executive officer of Tishman Construction Corporation, construction manager of the Freedom Tower. “From the very core of the building to the top of the spire, we’re using the best products, construction practices and processes available today, and that includes iCRETE. With its technology, iCRETE produces a stronger, more cost effective concrete that is environmentally sensitive. In fact, this is the highest strength concrete ever poured in New York—beating the previous record of 12,000 PSI.”
The iCRETE system, a patented state-of-the-art technology, will be used to produce 240,000 cubic yards of concrete for the Freedom Tower. During the design phase of the project, the building’s engineers required concrete used in the Freedom Tower to achieve a record breaking 14,000 pounds per square inch (PSI) of compressive strength.
In addition to physical and material benefits, iCRETE also offers environmental benefits. Since less cement is required for the iCRETE system, harmful carbon dioxide emissions are reduced by 40%—another industry breaking record.
iCRETE provides concrete producers with concrete mix designs and a production system that will have a transformative impact on their business as well as that of other industry stakeholders including contractors, architects, engineers, owners, developers and government agencies in America and throughout the world.
