WHAT IS IT?
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
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
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.
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.
- 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
- Non-conductive and completely transparent to magnetic and
- 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.
Basic recommendations for the use of
- 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
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
Due to fatigue, it cannot be used for prestressed concrete
The fiberglass rebar is wound into coils with a diameter of
1.2-1.7 m depending on the diameter of the rebar.
