NEW YORK--16 Feb--PRNewswire-AsiaNet/InfoQuest
- Manhattan's latest skyscraper and tallest residential building is using 280 million pounds of iCrete concrete mixes, reducing greenhouse gases, material costs, excavation time and labor.
- Strengths range from 6,000 psi to a top strength of 12,000 psi which is
demanded for the shear walls, columns and link beams.
- The use of iCrete for Beekman Tower means faster finishing times, reduced shrinkage, durability, less creep, and greater resistance to alkali-silica reactivity and freeze-thaw.

Rising majestically above the Manhattan skyline, just blocks from the World Trade Center Complex, is one of the most anticipated and historic construction projects undertaken since the original WTC towers were erected more than 40 years ago. At 76 stories, the $660-million Beekman Tower is destined to become the catalyst for the rebirth of lower downtown Manhattan.

Designed by famed Los Angeles architect and Pritzker Architecture Prize laureate Frank Gehry, the building will house 903 luxury residential apartments, each with its own unique floor plan. Occupancy is expected in the fall of 2010.
According to WSP Cantor Seinuk CEO Silvian Marcus, Beekman Tower will be totally made of concrete, unlike the Freedom Tower, which was steel with a concrete core. Indeed, when complete, Beekman will be the tallest residential building in New York City.
Concrete contractors will place about 65,000 cubic yards of cast-in-place reinforced, high-strength concrete on the main structure, with an additional 9,000 yards for the foundation. Upon completion, 280 million pounds of concrete will have been used, ranging in strength from 6,000 to 11,000 psi. According to Marcus, the shear walls, columns and link beams will be more than 12,000 psi. "Thanks to the high-performance concrete supplied to us by the California firm, iCrete, we were able to use a low water-to-cement
ratio," Marcus explained. "This allowed us to use 30 to 40 percent less cement."
The formula for the concrete mix, developed by iCrete, is, in and of itself, a source for potential LEED points. iCrete touts a reduction of 40 percent in greenhouse gas emissions resulting from less cement paste needed to bond the aggregates, reducing its carbon footprint. This also means less material costs, less excavation and less labor. In addition, iCrete offers faster finishing times, reduced shrinkage, durability, less creep, and greater resistance to alkali-silica reactivity and freeze-thaw. It also relies on less steel.
