水泥混凝土的孔结构分形特征研究

Research on pore structure fractal characteristics of cement concrete

混凝土细观结构中的孔隙具有大小不一、无序分布等特点,在对孔结构研究中需借助分形理论实施细观孔结构特征的描述。针对目前混凝土孔结构特征研究中多种孔结构分形理论进行比较分析,揭示不同理论在混凝土孔结构研究中的适用性,对于采用有效的分形理论来开展混凝土孔结构分布研究具有一定的指导意义。

Mesoscopic pore structure of concrete has many characteristics, such as sizes and the disordered distribution, so the description of the mesoscopic poise structure characteristics needs by means of fractal theory.Various pore structure fractal theory applied to analyze the concrete pore structure characteristics are compared, and reveals the applicability of the different theories in the concrete pore structure research.It is of a certain guiding significance to adopt effective fractal theory to study on distribution of concrete pore structure.
