The manufacturer “Kompozit Armatura” introduces a new product in the Balkans – composite reinforcing bar – GFRP (glass fiber reinforced polymer).

GFRP is a perfect solution and experiencing evolution in reinforced concrete technologies.

FRP( fiber reinforced polymer) is composite  material. Composite  materials  are  composed  of  two  or  more  partitions. GFRP   is composed by  polymer  matrix  reinforced  with  high strength fibers. The fibers are the element resistant to the tensioning forces and the matrix is the element that transmits the forces among the fibers, giving in the same time a protection from the external environment.

Benefits of GFRP Rebar:

• High resistance to corrosion and aggressive environments
• High tensile strength; 2 times higher compared to steel 1100-1300 MPa.
• Low weight; ¼  the weight of an equivalent size steel bar (savings on transportation)
• The lifecycle  in concrete is up to 100 years...

Composite rebar has found its application in many market segments:

Tunneling & Mining, Bridge Decks & sidewalks, Coastal Construction, Base slabs, Runways, Reconstruction, Repair Precast elements, Concrete Fences & Supporting walls, Water & waste water management, Desalinization, Water purification, Electric utility, Power generation, Electronics laboratories, MRI rooms chemical storage and architectural etc.

Many concrete structures subjected to aggressive environment, such as bridge, dam and offshore exposed to deicing salts, combinations of moisture, temperature and chlorides reduce the  alkalinity of  the  concrete  and  result  in  the  corrosion  of  steel bars.

CORROSION.

Steel is plentiful and inexpensive. It’s a great reinforcement to use if you are not responsible for the long-term maintenance of a concrete structure.

Steel  has no corrosion resistance and frequently it comes to the job site already rusting. Rust degrades the concrete, rusty stains often appear on surfaces of structures reinforced with it.

Structures built with black steel generally need some rehabilitation in as little as 5 to 10 years and frequently need major rehabilitation within 20 years.

To address corrosion problems, professionals have turned to alternative metallic reinforcement, such as epoxy-coated steel bars, cathodic protection, and increased concrete cover thickness. While effective  in  some  situations,  such  remedies  may  still  be unable to completely eliminate the problems of steel corrosion.

SOLUTION.

No corrosion effect has been detected on GFRP. The prime reason for using GFRP is for concrete longevity.

Properly reinforced GFRP concrete slabs exposed to heavy fatigue loads (like driveways, bridge decks) will have less cracking and are projected to last up to 20 times longer than similar structures reinforced with conventional steel.

     

INDUSTRIAL APPLICATION:

  

   

   

The estimate of repair cost for existing highway bridges in the USA is over $50 billion, and $1 to $3 trillion  for  all  concrete  structures.  

In  Europe,  steel corrosion has been estimated to cost about $3 billion per year.
