Accelerated test method for determination of resistance to carbonation

The carbonation of concrete and mortar can cause reinforcement corrosion. Therefore, the resistance to carbonation of concrete is an essential parameter for the evaluation of the durability of reinforced concrete. So far, it was not possible to develop a uniform accelerated test method throughout Europe for the determination of the resistance to carbonation, since it was not clear how and if physical and chemical parameters change as a result of accelerated carbonation in comparison to natural carbonation. Due to the fact that carbonation in nature – depending on exposure and composition – may...
