水泥颗粒微观分维与宏观流动性关系的研究

Study on relationship between microcosmic fractal dimension of cement particles and macroscopical fluidity of cement

将微观分维作为表征水泥颗粒的形态参数;用数字显微系统测算了5种水泥颗粒样品的微观分维,研究了水泥微观分维及其与粉体流动性指数的关系,结果表明:水泥粉体微观分维与其流动性指数呈线性负相关。

The morphology of cement particle was characterized by the microcosmic fractal dimension. Five kinds of cement particle samples, which were measured with digital micro system, were used to find out the relationship between microcosmic fractal dimension of cement particle samples and the macroscopical fluidity of cement. The results indicated that the microcosmic fractal dimensions of cement particle sample and macroscopical fluidity indexes of cement were negative linear correlation.
