Carbonation of concrete is discussed in connection with corrosion of reinforcement. Depending on the depth of carbonation, it can be decided whether corrosion has already started or whether corrosion has already started. This test is called the carbonation test.
On the other hand, concrete carbonation offers positive effects, such as increasing the compressive and tensile strength of concrete.
The following factors mainly affect carbonation.
- Relative humidity
- temperature
- CO 2 concentration
There are several methods for determining the degree of carbonation. Of these, the following stand out.
- IR spectrum analysis
- pH indicator analysis
There is more to discuss about carbonation. For more information on carbonation and its testing methods, etc., see the last part of the article “ Non-destructive testing of concrete “.
