Investigation of the shape, size, angularity and surface texture properties of coarse aggregates
Highlights ► The actual three dimensional shapes of coarse aggregates were investigated. ► The statistical distributions of the aggregate sizes were studied. ► An indicator was developed to characterize the angularity and surface texture.
Abstract The shape, size, angularity and surface texture properties of coarse aggregates were studied in this paper. Aggregates with different shapes were separated manually and the percentage by number of each shape was computed. The three sizes (length, width and thickness) of aggregates were extracted using an image analysis approach and their statistical distributions were studied. An indicator called angularity and surface texture (AT) index was developed to characterize the combined effect of the coarse aggregate angularity and surface texture based on two-dimensional aggregate images. The statistical distributions of the AT indices of different sized limestone and basalt aggregates and their composite AT indices were studied. The void contents of different sized limestone and basalt aggregates in loose condition were tested to validate the AT index.
