Composite rebar is lighter than steel, stronger than steel, more
reliable steel.
Composite rebar for reinforcing concrete structures FRP-Rebar
(Fiber Reinforced Plastic Bar is the polymeric armature
strengthened by a continuous fiber) is a fiberglass or composite
rods with a diameter of from 4 to *0 mm, length up to *2 meters (it
might be rolled in a coils) with the ribbed surface of the helical
profile. The composite armature is intended for application in
concrete structures with prestressed and unstressed reinforcement
instead of traditional steel reinforcement. Available in sale
FRP-rebar is made of plastic reinforced with aramide fibers (AFRP),
carbon fibers (CFRP), glass fibre (GFRP) and basalt fibers (BFRP),
Packed in a polymeric matrix. The most widely used fiberglass and
basalt-plastic rebar. The fiberglass armature due to their
dechevsky with enough good characteristics of basalt-plastic and
fittings due to its unique resistance to all kinds of chemical
environments. Typical products FRP: rods, rods and cables. There
are different types of shape (square, round, solid and hollow) and
deformation systems (exterior deformation of the winding fibers,
sand coatings and separately formed
deformations).
Than composite rebar steel better?
stronger than steel in 1,**2 times;
lighter than steel 3.**4 times;
has a high modulus at small elongation, high resistance to stress
loads;
it has excellent rheological
characteristics;
no corrosion, only very slightly changes its mechanical properties
under the influence of acids, salts and
alkalis;
is a dielectric, radio-transparent, magnitometry (excluded the
change of strength properties under the influence of
electromagnetic fields);
does not lose its strength properties under the influence of
ultralow temperatures;
thermal expansion coefficient of the composite armature corresponds
to a CTE of the concrete then that excludes breaks in the
reinforcing and cracks formation in the protective layer of
concrete under the influence of temperature
cycles.
By what the frp-rebar is better than the steel
one?
it is stronger than the steel armature in 1,**2
times;
it weighs 3,**4 times less than the steel
armature;
it has the high module of elasticity when the relative extension
coefficient is low. Besides it has strong durability as respects to
stress loads and also possesses good flow curves;
it doesn\'\'t corrode, changes its mechanical properties rather
weakly under the influence of acids, salts and
alkalis;
it is a dielectric and also is radio transparent and magnetically
inactive (the change of strength properties of composite armature
under the influence of electromagnetic field is
excluded);
it keeps its strength properties under the influence of ultralow
temperature;
the thermal expansion coefficient of the composite armature
corresponds to the thermal expansion coefficient of the concrete
then that excludes breaks in the reinforcing and cracks formation
in the protective layer of concrete under the influence of
temperature cycles;
the coefficient of heat conductivity of the composite armature is
low tenfold than the one of the steel armature (it is commensurable
with the wood). The composite armature is the basic reinforcing
material for multilayered heat saving building constractions, it
provides an effective heat insulation and the absence of cold
bridges during the long operation life of the multilayered
heat-insulative wallings and facades, all these characteristics are
achieved owing to the low coefficient of heat conductivity, high
corrosion resistance and the absence of gradient frost actions of
the heater in length of the armature.
