U.S. Concrete Precast Group has completed the production of 130 prestressed, green concrete U-beams for the Sky Train project, a massive, $1 billion-plus public works effort now under construction at the east end of the Phoenix Sky Harbor International Airport. U.S. Concrete secured the project in 2009 with lead contractor Hensel Phelps Construction Co. Production of high-strength U-beams began at the company’s Phoenix manufacturing facility in February 2010, utilizing environmentally friendly concrete mix design, EF Technology, which used 12.5 percent fly ash replacement and can have a carbon footprint 30 percent lower than standard concrete mix designs.
