“The iCrete System gives us the confidence that we have
the best concrete to build the Freedom Tower, the most important building we have ever constructed.”
Renzo Collavino, President

iCrete at the core of the new Freedom Tower.

For the construction of the Freedom Tower at One World Trade Center in New York, the Port Authority specified higher strength concrete than had ever been made in the state. A minimum seven million elastic modulus was required for all core walls, some of which were more than nine feet thick. Along with high strength, a low heat of hydration was also required to ensure no thermal cracking of the walls. High strength concrete traditionally means increasing the amount of cement, high heat and low water. This combination was an additional challenge to the ability to pump and place the mix. iCrete was the only company whose technology could meet all these stringent requirements. After installing the technology and certifying a local concrete supplier, the iCrete System was able to meet all the job requirements through a unique materials optimization and with a lower environmental footprint than ever achieved for this strength product. Quality assurance testing by the Port Authority during the first pour showed that the iCrete mix and technology had unparalleled consistency, it required less cement and the compressive strength exceeded 16,000 PSI.
