Online video explains how CarbonCast Double Tees are up to 8 percent lighter and resist corrosive elements

CarbonCast Double Tees with C-GRID carbon fiber grid reinforcing are showcased in a new video.

A new video from AltusGroup (altusprecast.com), a North American network of 14 precast concrete manufacturers dedicated to innovation, is intended to educate parking garage owners and engineers about the use of carbon fiber grid reinforcing in the flange of precast concrete double tees. The video appears on AltusGroup’s website and YouTube channel (youtube.com/altusprecast).

The video details the design and production of CarbonCast Double Tees, which use C-GRID carbon fiber grid as flange reinforcement replacing conventional welded wire mesh. Because carbon fiber grid is non-corrosive and four times stronger than steel by weight, AltusGroup precasters can use less concrete cover atop the reinforcing. A typical 4-inch thick flange can be thinned to 3-1/2 inches, saving six pounds per square foot in weight and reducing the structure’s carbon footprint.

The video also explains how non-corrosive C-GRID can eliminate the cost of adding corrosion-inhibiting admixtures to the concrete or the expense and hassle of applying sealers to the deck surface before commissioning and reapplying them every five years.

Also addressed in the video is how CarbonCast Double Tees can meet ASTM E119 requirements for a one-hour fire rating. Calculations based on ICC codes and accepted design criteria show that, just like steel mesh reinforced tees with the same flange thickness, they can provide a two-hour fire rating.
