| Abstract: | Concrete demonstrated a series of fractal characteristics in the process of its formation and work.This paper mainly introduced thed testing methods of concrete porosity,the calculation method of conerete pore fractal dimension,used the pressure mercury method tested the pore structure data of six groups concrete,calculated their porosity fractal dimension,and combined with SEM micro-analysis the effect of admixture on concrete porosity characteristies was evaluated. |
