混凝土孔结构分形特征的研究现状与进展

Current situation and development of fractal characteristic of pore structure of concrete

混凝土孔结构是一种分形介质,其孔形、面积、体积等均具有明显的分形特征,随着对分形理论和混凝土孔结构研究的深入,混凝土孔结构分形特征的研究取得了长足的进展。为探讨混凝土孔结构分形特征研究的发展方向,对现有研究成果进行了归纳总结,介绍了目前已建立的混凝土孔结构分维模型,并对现有相关文献中的重要结论进行了相应的评述,最后提出了混凝土孔结构分形特征研究领域中有待解决的问题。

The pore structure of concrete is a kind of fractal object.The profile, area and volume of pores all show fractal characteristic obviously.As increasing attention was paid on fractal theory and pores of concrete, considerable progress has been made on research on fractal of pore structure of concrete.In order to find the development indirection of fxactal of pore structure of concrete, the relative research results were collected and analyzed.The existing fractal models of pore structure of concrete were introduced, and important conclusions of the papers were commented. At last, the problems waiting to be solved on fractal of pore structure of concrete were put forward.
