The Carbonation Depth Test, specified in AS 1012.20, is a method used to assess the depth of carbonation in concrete structures.

The Carbonation Depth Test determines the depth to which carbonation has penetrated into the concrete.

This depth is usually measured from the exposed surface of the concrete to the point where the concrete’s pH level is around 9 or higher, indicating that the concrete is sufficiently alkaline to prevent corrosion of embedded steel reinforcement.

By conducting the Carbonation Depth Test according to AS 1012.20, engineers can evaluate the carbonation resistance of concrete structures and implement appropriate measures to mitigate the risk of reinforcement corrosion, ensuring the long-term durability of the infrastructure.
