Description
C-Bar® is a fiber-reinforced polymer (FRP) bar used as an alternative to conventional steel rebar in the reinforcing of concrete structures. C-BAR® is 1/4 the weight of conventional steel rebar and due to the material's non-corrosiveness, concrete structures built with C-BAR® are significantly more sustainable than those built with steel.
Bending
C-BAR® is also the only FRP rebar that can be bent into specific shapes during manufacture-the result of a patented fabrication process as flexible as uncured rebar itself. Marshall is unique in the industry, adapting quickly to change orders during rapid productions and featureing ship-on-the-fly capabilities to meet the needs of every customer.
Project Highlights
1996, Buffalo Creek Bridge:
C-BAR® is in the US's first vehicular bridge that features a FRP rebar-reinforced concrete deck. This two-lane bridge is located in Brooks County, West Virginia. After construction, the structure passed extensive load testing and continues to meet all expectations.
1997, Kennedy Mansion Seawall:
Before its renovaition, this ocean barrier was more than 65 years old and had numerous cracks up to 1/4 inch wide. Approximately 40% of the wall's steel rebar had corroded due to saltwater exposure and harsh wet/dry cycling. The cured wall stands 190 feet long and 17 feet high. C-BAR® was selected for this restoration project because of it's non-corrosiveness, significantly reducing future maintenance requirements. C-BAR®'s interlocking surface also provides a stronger bond with the wall's concrete, and its light weight resulted in significant savings in transportation and handling costs.
2002, Two-Mile Creek Bridge:
This two-lane vehicular bridge was built in Clark County, Kentucky. The 61-foot-long and 31-foot-wide concrete deck was the first to be reinforced exclusively with C-BAR®. Test results after three years of continuous use confirm C-BAR®'s effectiveness and durability.
