Abstract

This paper presents the entropy as a method for texture analysis of Scanning Electron Microscope (SEM) images obtained from mineral aggregates. The SEM images were used in order to avoid the interference of inherent color variations on aggregates surfaces. Three types of aggregates (gabbro, basalt and gravel) were used for surface texture analysis. Entropy was used to analyze and quantify the roughness of rock fragments (aggregates). The presented method was able to distinguish aggregates with different roughness and to group aggregates with similar roughness.
