In the field of civil engineering such as highways and bridges, concrete is the core building material, and its strength and stability directly determine the load-bearing capacity and service life of the structure.
As a common environmental degradation phenomenon in the service life of concrete, carbonation has a complex bidirectional effect on strength – it may increase surface strength in the short term, but also weaken overall structural performance in the long term.
A deep understanding of the intrinsic relationship between carbonation depth and concrete strength is of crucial guiding significance for engineering quality inspection, structural durability assessment, and maintenance decision-making.
