It seemed a plausible hypothesis that the head loss should depend rather on the total surface of the sand grains than on the fineness modulus; with the sieve series used (Tyler sieves used by ABRAMS) the surface modulus may be found from the formula: [img ] where P 1 = percentage passing through the No. 100 sieve; P 2, P 3, etc. =percentage between 10048, 4828, etc. The following are .

Fineness modulus (FM) of aggregates can be an intimidating term, but it''s just an empirical value that describes the average size of particles in a sample of aggregate. This factor provides a basis to select estimated proportions for a concrete mix design, but its real influence is not always understood.
