摘要：
Based on multifractal theory and quantitative stereological method, nonuniform distribution of corrosion morphology in reinforcing steel bars were analyzed and corresponding multifractal spectrum was proposed in this study. The results showed that the corrosion morphology of reinforcing steel bars is multifractal. All the Delta f values are greater than 0, which indicating the distribution of corrosion depends on the maximum subset of probability. The width of the multifractal spectrum (Delta alpha) increases linearly as the corrosion mass loss ratio increases, which is a scientific index in characterizing the nonuniform corrosion degree of reinforcing steel bars.
