Paper Title:
Air-Entraining Concrete Bubble Distribution Fractal Dimension and Anti-Chloride Ion Diffusion Characteristics
  Abstract

Usually resistant to salt water corrosion of concrete prepared with fly ash and slag grinding fine admixture, however, such mixed concrete frost resistance is bad, resistant to seawater freeze-thaw performance is worse, usually with higher air-entraining, can overcome the defects. In the project, even if the liquidity of concrete is very good, the difference in bubble size and its distribution is very complicated. In order to prepare the concrete with high resistant to seawater freezing-thawing and corrosion, this paper studied on the relationship of the high air content of concrete with high resistance to sea water freezing-thawing and chloride ion diffusion coefficient. It was found that concrete air content, bubble fractal dimension and electric flux has good correlation, concrete anti-chloride ion diffusion ability can introduce bubbles cluster fractal dimension and bubbles distribution fractal dimension to characterization. With the increase of fractal dimension, the concrete resistance to chloride ion diffusion capacity enhanced. the complexity of the bubble was reflected from the bubble distribution fractal dimension, which objectively describes the gradation of bubbles, bubbles gradation improved greatly improve the concrete anti-chloride ion diffusion capacity.
