Here is the final paper of the year! Our latest work has been published in Cement and Concrete Research. This paper builds upon our previous work, focusing on concrete under general atmospheric conditions and exploring how to evaluate the maximum degree of carbonation (CO2 fixation) under different exposure conditions. It experimentally demonstrates that the impact of the wet and dry cycle is most influenced by higher humidity levels and discusses the underlying mechanisms. Additionally, we delve into the mechanisms behind the differences in carbonation rates observed under various humidity conditions.
