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 40 mm, length up to 12 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 1,5-2 times;
lighter than steel 3.5-4 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 1,5-2 times;
it weighs 3,5-4 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.
