Abstract: The size distribution, particle shape and chemical composition of four kinds of slag powders were studied using fractal theory. The results show that the four kinds of slag powders have good self-similarities on the particle size distribution， particle shape and chemical composition. The slag powders have the characteristics of fractal structure. The fractal dimension of slag powders is between 2 and 3 and it increases with the powder texture fining. The single slag particle fractal dimension is about 1.01. The cationic field intensity of the main chemical composition and its corresponding cumulative distribution have a self-similarity. The higher the fractal dimension is, the better the quality of slag is.

Keywords: fractal dimension; slag powder; fractal charaltenitl; self-similarity
