However, experimental evidence suggests it is inferior to the fineness modulus where aggregates for concrete are concerned. A further item is the ‘D-m-s method’ in which the fineness modulus and specific surface are both used for grading evaluation, to combine the advantages of the two methods. Finally, an analogy is used in an attempt to explain why the logarithmic average particle size
