In a completely different area and facing totally distinct issues, aluminum smelters are subjected to an overheating of the steel concrete reinforcement in the pot room slabs, which in turn damages the concrete.
Factually, the high voltages used in the alumina transformation process and the closed loops/coils created by the reinforcement pattern in the slab cause, by induction, significant losses in energy and ultimately make of that steel a heating element. This heat build-up, which can reach a few hundred Celsius degrees, triggers an important expansion of the steel and leads to concrete cracking by weakening the link between itself and the reinforcement.
With the product V•ROD of Pultrall...
V•ROD being an electromagnetically neutral solution, it will not be influenced whatsoever by the magnetic fields associated with these processes and will therefore avoid having to use stainless steel or grounding all the regular steel rebar grid. Ultimately, V•ROD will make you save money and ensure the long-term durability of the concrete structures, without all the inconvenient of the other suggested solutions.

See the following documents.
V•ROD rebar does not rust, even in the harshest environments. It does not react to salt, chemical products or the alkalinity present in concrete.
V•ROD rebar does not create a thermal bridge within structures.
She is almost 4 times lighter than steel rebar. It is much easier to handle and, in most cases, one truck load will be sufficient to carry the rebar required on an entire project.
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 produced by pultrusion offers a tensile strength that can reach more than five times that of steel.
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 of straight bars as well as angles and led lengths of special bent sections are prepared in the plant.
