Revolution in Concrete Construction – The Solution for Corrosion
Pultrall is a pioneer in non-metallic concrete reinforcement solutions and an undisputed leader in the number of road infrastructure project completions in North America. The technology of reinforced concrete is facing a serious degradation problem in structures due to the corrosion of steel rebar. Fibre-reinforced polymer (FRP) rebar has proven to be the solution. Lightweight, corrosion resistant, and offering excellent tensile strength and high mechanical performance, V•ROD rebar is installed much like steel rebar, but with fewer handling and storage problems.
Thanks to V•ROD, builders and owners of structures can take advantage of a major evolution in reinforced concrete technology. This means:
• More secure structures
• Non-existent corrosion
• Reduced life cycle cost of 15 to 30%
The advantages of V•ROD rebar are backed by years of testing and actual field results in the most demanding conditions. From now on, limitations will lie with the concrete, and not the reinforcement.
V•ROD rebar does not rust, even in the harshest environments. It does not react to salt, chemical products or the alkaline present in concrete.
V•ROD rebar produced by pultrusion offers a tensile strength up to twice that of steel.
V•ROD rebar offers a level of thermal expansion comparable to concrete due to its 80% silica content.
V•ROD rebar does not contain any metal; it will not cause any interference in contact with strong
magnetic fields or when operating sensitive electronic instruments.
V•ROD rebar can be delivered at the right time and in the exact quantity needed at the site. Various specifications such as the length, angles or bends of special sections are prepared in the plant.
V•ROD rebar is 4 times lighter than steel rebar. It is much easier to handle, and in most cases, one truck load will be sufficient to supply the rebar even for an entire project.
V•ROD rebar does not create a thermal bridge within structures.
Given the present value for total costs of maintenance and demolition, using V•ROD technology represents a savings of 45 to 60%.
Given the present value of the overall life cycle cost, using V•ROD
technology represents a savings of roughly 15 to 25%.
If we add unknown factors such as the fact that fragile epoxy coating
may be compromised due to impact when installing rebar, the savings
provided by using FRP increases from 15 to 30%.
V•ROD rebar allows costs to be eliminated related to the use of expensive membranes.
It is possible to use conventional concrete instead of low permeability concrete with added corrosion inhibitors.
Reduced weight allows for the handling of more rebar at the same time and reduces installation time.
V•ROD rebar is manufactured according to set standards, has been approved by ISIS Canada and is included in CSA design standards.
Standard specifications are now available to engineering firms for quality control of projects, including independent on-site inspection.
Installation methods in concrete have been standardized in accordance with those of steel.
