| 摘 要： | 本文在扫描电镜下观察了水泥石试片单轴压缩时微裂纹的运动，测量不同应力水平下微裂纹的分形维数，给出了分形维数的演化规律，分析了这种演化规律与宏观大学性能的相关性。对于水灰比W/c=0．3，0．4，0．5三种试件的观察结果进行了对比分析。

| Abstract: | With a view to studying the motion of microcracks under axial compression,samples ofhardened cement paste are observed under the SEM. Fractal dimensions of microcracks atvarious stress levels are measured. The evolution of fractal dimension is then given. Correla-tion of the evolution with macroscopic mechanical behavior is analyzed. Samples with w/c=0. 3,0. 4,0. 5 are compared and their observation results are analyzed. |
