The new iCRETE system, which achieves a record 14,000 pounds per square inch of compressive strength, is being used to build the Freedom Tower at Ground Zero in New York City. Both the 1,770-square-foot tower and the 186-square-foot inner safety core supporting the superstructure will be built with iCRETE.
The iCRETE system, a patented 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 tower to achieve a record-breaking 14,000 pounds per square inch (PSI) of compressive strength, which is the highest strength concrete ever poured in New York – beating the previous record of 12,000 PSI.
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 percent – another industry record.
