Methods of concrete accelerated carbonation test: a review
Ahmed Merah
Abstract
Developing a method to predict the behavior of cementitious materials against natural carbonation, which causes degradation in reinforced concrete structures, has been an area of interest for researchers. Although the natural process is gradual and takes years to manifest, accelerated carbonation tests have been devised to simulate this process in a shorter duration. Nevertheless, various factors have an influence on the accuracy of these tests, in predicting natural carbonation, including CO 2 concentration, humidity, temperature, type of cement and aggregate, curing time, and duration of exposure to CO 2 . This review emphasizes the significance of considering these factors when using accelerated carbonation tests to evaluate the durability of concrete and to prevent corrosion. Taking these factors into account can help ensure that designers estimate the service life of concrete structures accurately and that appropriate measures are taken to mitigate any potential damage caused by natural carbonation.
