The bacteria in the plaque feed on ingested sugars and produce an acid that leaches calcium and phosphate from the teeth.
From Wikipedia, the free encyclopedia. Rebar is common steel reinforcing bar, an important component of reinforced concrete and reinforced masonry structures.It is usually formed from mild steel, and is given ridges for better frictional adhesion to the concrete.poxy-coated rebar or stainless steel rebar may be employed in these situations at greater initial expense, but significantly lower expense over the service life of the project. Fiber-reinforced polymer rebar is now also being used in high-corrosion environments.
