The technology of reinforced concrete is facing a serious degradation problem in structures due to the corrosion of steel rebar. In Australia, the repair costs are estimated to be close to 26 billion dollars.
Several options have been explored, most notably the use of galvanized steel rebar, epoxy coated or stainless steel. The results, however, have been disappointing as these solutions have turned out to be less than effective or cost prohibitive.
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.
