  • Fineness Modulus - an overview | ScienceDirect Topics

    Aggregates which mainly pass a 4-mm sieve are termed 'fine' aggregates. The coarseness or fineness of sands is described by d/D sizes in mm of 0/1, 0/2 and 0/4. A further classification is provided based on either the percentage passing a 500-μm sieve (Table 15.7) or the fineness modulus, for coarse, medium and fine grading sands (C, M and F).
