Word of the Day : Rebar

According to Wikipedia :

"A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is given ridges for better frictional adhesion to the concrete. It can also be described as reinforcement or reinforcing steel."

Like many of the words in this category.I have no idea why it popped into my head or where I had heard it before.
