WHAT IS IT?

Fiberglass reinforced polymer rebar (also known as
composite reinforcement (rebar), fiberglass reinforcement rebar) - a great
choice for reinforcement of foundations and concrete floors. Suitable for
reinforcement of concrete elements, especially those intended to be operated in
aggressive environments.

Composition
The properties of composite reinforcement are determined by the fiber used to
make the reinforcement. For example, fiberglass rebar produced by different
manufacturers have almost identical properties because glass fiber is used for
longitudinal reinforcement. And namely the type of fiber has a decisive
influence on the tensile strength and modulus of elasticity of the final
product.

The main function of the resin is to combine the fibers for joint work and to
distribute the stresses from the surface of the rod (in contact with the
concrete) into deeper layers.

The resin also performs a protective function and forms a layer on the surface
which prevents alkali or other chemical elements from entering the deeper
layers of the reinforcement.

Use
Reinforcement in monolithic elements is used only to take over tensile and
compressive stresses. Fiberglass rebar "work" poorly for compression,
so it is mainly used in the elements to take over the tensile stresses and to
form the transverse reinforcement in order to take over the stresses in the
diagonal of the incision. Reinforcing bars (both steel and composite) are in no
way counted as bending elements. They are considered only as a component of the
reinforced concrete element and performs partial takeover of tensile or
compressive stresses from concrete, in particular tensile, concrete is much
more resistant to crushing than tensile.

PROS AND CONS

Pros:

  • The tensile strength
    is 750-1020 MPa, it depends on the diameter of the rod and is from 1.5 up
    to 2 times larger than S500 grade steel.
  • Density is about 2000
    kg/m3, and is about 3.9 times lighter than steel.
  • It deforms only
    elastically so it can be rolled into rolls and straightens when released,
    does not remain bent.
  • Due to its relatively
    low weight and the ability to roll, it is convenient to transport and
    carry. Also the amount of residue is reduced.
  • Thermal conductivity
    coefficient about 0.34 W/(mK) (about 130 times less conductive heat than
    steel).
  • Non-conductive and completely transparent to magnetic and
    electromagnetic fields.

Cons:

  • The modulus of elasticity is 35-45 GPa (also depends on the
    diameter and is about 6-4.6 times lower than steel).
  • Operating temperature up to 105 °C (steel characteristics start
    to decrease from 300 °C).
  • Fiberglass (regardless of its binder) have a property of
    fatigue. Therefore, the continuous load should not exceed 50-60% of its
    maximum bearing capacity.

RECOMMENDATIONS

Basic recommendations for the use of
fiberglass reinforcement:

  • Particularly suitable for reinforcing elements that will be exposed to aggressive media (tanks, canals, farm floors and gutters, roads and car parks, fertilizer depots and etc.). In such elements, it solves the weakest side of steel - that is corrosion resistance.
  • It is very suitable for forming the connecting reinforcement of multilayer partitions to reduce heat loss from the building.
  • Particularly suitable for buildings that require magnetic or electromagnetic transparency (electrical switchboards, magnetic resonance rooms, etc.).
  • Suitable for elements without highly concentrated stresses, as well as for elements which will be operated in a humid or aggressive environment (foundations, floors, retaining walls, plinths, etc.).
  • For structural frame elements (columns, beams, floor slabs, etc.) may only be used after recalculation by a responsible qualified designer-constructor. Due to the much lower modulus of elasticity the deformations of fiberglass reinforcement will be about 4.6-6 times greater compared to steel under the same load. So it is necessary to estimate this and increase the total cross-sectional area of the reinforcing bars accordingly. In the general, use fiberglass rebar in such elements is irrational unless there are very good reasons why steel rebar is unsuitable to use (due to required magnetic transparency or corrosion requirements).
  • Due to fatigue, it cannot be used for prestressed concrete structures.

PACKAGING

The fiberglass rebar is wound into coils with a diameter of
1.2-1.7 m depending on the diameter of the rebar.

NOTE

  • The fiberglass rebar is not UV stabilized.
  • When the product is unwound from the coil, the rebar may have a slight bend and may be not completely straight.
