Specification
Rebar is made of unfinished steel, making it susceptible to rusting. As rust takes up greater volume than the iron
or steel from which it was formed, it causes severe internal pressure on the surrounding concrete, leading to cracking,
spalling, and ultimately, structural failure. This is a particular problem where the concrete is exposed to salt water, as
in bridges built in areas where salt is applied to roadways in winter, or in marine applications. Epoxy-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
Most grades of steel used in rebar cannot accept welding; such as, to adjacent steel plates or as means to bind single
pieces of rebar together. However, special grades of rebar steel and welding rods make welding by expert welders possible.
To prevent workers from accidentally impaling themselves, the protruding ends of steel rebar are often bent over or covered
with special plastic "mushroom" caps.
