Tensile loads

(Carbon reinforcement)

Concrete is recognized for its strength in compression but it is greatly disadvantaged when submitted to tensile loads. It is for this very reason that steel or other types of reinforcements are used in conjunction with this material. In pre-stressing, compressive stresses are introduced in the products in order to balance the effects of the external loads that will be applied on the concrete elements. The ultimate goal of pre-stressing is to limit/eliminate the occurrence of cracks in the structures subjected to service loads as well as reducing the overall size of these elements, eventually making them lighter too.

Although steel has been used in pre-stress applications for over 60 years, we are presently witnessing the emergence of revolutionary precast pre-stressed concrete products manufacturing techniques with the increasing interest for composite material concrete reinforcing bars. This changing environment has greatly influenced the development of a technology that would make pre-stressing with corrosion resistant tendons a reality.

With the product V•ROD of Pultrall...

The CARBON V•ROD product from Pultrall is the answer to this new requirement. With a guaranteed tensile strength equivalent to that of the steel ones, the #4 (13M) Carbon V•ROD tendons, used in conjunction with the FIBERLOC anchoring system, make the fabrication of precast pre-stressed ''steel-free'' and ''long-lasting'' concrete elements possible.
