I’d be very careful about using it unless you can get it sandblasted or spend a lot of time wirebrushing the rust off of it. The rust is a sign that it’s been wet. The rust will continue to build up on the rebar in the concrete, as it builds up it will expand eventually cracking the concrete.
What does rust look like?
The first signs of rust are tiny specks or spots on leaves that range in color from orange to rusty-brown, brownish-yellow, purple and red. Left untreated, the spots get bigger and turn into bumpy-looking pustules. Eventually, the pustules break open and release spores that are spread by wind or splashing water.

We have known for many years that as rust forms on metal installed in masonry or concrete, the rust expands up to seven times the original thickness of the metal. The force of this expansion, if confined, can reach as high as 9,000psi.
What kills rust?
PREPARATIONGenerously sprinkle baking soda over the rusted object until it is covered in a thick layer. Pour just enough water over the baking soda to create a thin paste.Using a scrubbing pad or brush, scrub the mixture on the object until all rust has been wiped away.Wash, dry, and use as normal.
Does iron rust underwater?
Oxidation of iron When iron is in contact with water and oxygen it rusts. If salt is present, for example in seawater or salt spray, the iron tends to rust more quickly, as a result of electrochemical reactions. Iron metal is relatively unaffected by pure water or by dry oxygen.
Can you stop rust once it starts?

Can rust spread from one gun to another?
Rust isn’t like cancer and doesn’t spread to other items but there are two attributes of rusty metal that can cause rust on other items nearby and those are: Rust is a hygroscopic material which means it absorbs moisture so rusty items can increase the moisture (humidity) in closed containers such as a safe.
Does rust spread on its own?
Rust does not spread through contact like a biological infection. Instead, the process of iron oxidization occurs independently based on the conditions surrounding a particular piece of metal. … Iron alloys will have different corrosion rates based on their makeup.
Is water needed for rusting?
Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Boiling the water removes the oxygen and the layer of oil prevents it from re-entering.
Does rust spread under paint?
Another big problem with rust is that even if the entire surface is well protected with paint, if rust starts to develop on the back of the metal where it cannot be seen, or in a hidden corner, or even where the paint gets scratched, this rust will continue to spread under the surrounding paint – eventually causing the …
Do rust converters actually work?

Does water speed up rusting?
There are certain factors that can speed up the rusting process. For example, water speeds up the reaction. Other substances, such as salt, can also increase the speed of the rusting process. To prevent rust, iron can be coated.
What is the best homemade rust remover?
