This paper discusses the durability of concrete through multi-scale structural optimization, and studies it from macro, meso and micro levels by combining experiments and theoretical analysis. On the macro scale, the mechanical properties and structural strength of concrete are evaluated, and it is found that the higher the water-cement ratio, the more obvious the decrease of compressive strength in carbonation environment. The fracture development and pore structure were observed at mesoscale, and it was pointed out that the cracks in the samples with high water cement ratio expanded rapidly and the pore structure was loose. The research shows that multi-scale structural optimization is of great significance to improve durability and provides scientific basis.
