    AFS grain fineness number

    The relevance of the grain fineness number can be ascribed to the fact that this values is proportional with the number of grains per unit of weight and with the specific surface area of the sand. For approximate calculation of the AFS grain fineness number, the value of the theoretic specific surface area is multiplied by the factor 0.57..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.
