To study the effect of corrosion of reinforcement in a concrete, there are many tests available-

Half cell potential tests

Chloride penetration test

UPV tests

X-ray , Gamma radiography ( Becoming popular)

Many other tests are available but these are more common and widely used.

Thanks So much Siddharth Nahta .. i will google those methods

We use the following tests to get an idea about the risk of steel corrosion: Ficktest, waterabsorption by capillarity, chloride penetration (submersion, capillarity) and Half cell potential tests.

Thanks Joseph, those are the methods to study the risk, what about looking for something to prevent the corrosion, for exemple in the acidic medium, we use to investigate the inhibition effect by organic compounds, for the steel in cement how we can reduce the corrosion rate of the metal.

Maybe you can put the concrete in an environment that will lead to forced corrosion. Then put the concrete with the prevention method in the same environment. After a while, remove the concrete from the iron and measure the rate of corrosion. Weight loss measurements or Electrochemical tests could be used for this.  

Weight Loss, Yes i got it, i will try this technique as soon as possible. Best Regards

Hello Mohamed El Azzouzi,

You can use Weight loss method and electrochemical methods like OCP, Tafel, Anodic, cyclic polarization, Linear Polarization etc.

Hi Mohammed,

You can get knowledge from the following event
