### Fineness Modulus of Aggregates: The Inside Scoop - Gilson Co.

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."
