摘要：

The scope of this paper is to investigate by an automatic image analysis technique the dispersion of phases in concrete. Three morphological and statistical tools were used: co-occurrence matrices, and simple and crossed-covariance. It was shown (1) that there is a repulsion between gravel, (2) that gravel and air-voids are surrounded by matrix (cement paste and sand), and (3) that the dispersion of gravel and air-voids is perfectly uniform.
