In the design of concrete mix proportions, the amount of cement used is the core parameter that directly determines the total amount of cementitious materials, the composition of hydration products, and the compactness of the microstructure of the concrete, thereby profoundly affecting the carbonation depth from three dimensions: “alkali reserve supply”, “pore structure optimization”, and “interface transition zone improvement”.
Scientific clarification of the intrinsic relationship between the two is of crucial guiding significance for improving concrete carbonation resistance and extending structural durability through mix proportion optimization.
