Everyone knows the common problem of carbonation. The term carbonation is used for damage to (usually reinforced) concrete. Carbonation occurs in steel constructions in concrete, so-called reinforcement. These constructions are used in the construction of bridges, viaducts and in buildings. When carbonation takes place, the reinforcement in the concrete starts to rust.
Fiber Dowels products solve this problem. Fiberglass products used in the concrete are not sensitive to rust. The lifespan of the pavement will be extended by using these materials.
Nowadays, everyone compares fibreglass with the familiar steel. We have noticed that projects are still mainly price-driven. Glass fiber reinforced polymer, chemically inert reinforcement, is an economical way of achieving a long service life of your project. Old reinforcement materials might seem inexpensive, however, they can cost you a lot of money in the long-term. By applying fiberglass rebar, you can not only save money in long-term but also make your project completely rust free.However, when the focus will be on durability, quality and extending the lifespan, these products can be applied much better.
The table above indicates the amount of corrosion penetration of the steel in mils per year (mpy) based on the measured corrosion current density, or Icorr. Icorr is the loss of electrons that occurs at the anodic site of the corrosion cell and is measured in microamperes per square centimetre (μA/cm2).
The above table gives corrosion current density values in both μA/cm2 and microamperes per square inch (μA/in2) and their relationship to when expected damage would occur to a reinforced concrete structure.
