Aspects of aggregate fineness are already illustrated in Fig. 2.35 showing that concrete mixtures with fine aggregates are more resistant against water jet erosion. A design parameter that characterises aggregate fineness is the k-number (graining number). The larger the k-number the higher the amount of coarse particles.
