Fineness Modulus of Cement and Aggregates - IIT Bombay

Fineness Modulus of Fine Aggregate. Fine aggregates is the sand used in mortars. The size of the fine aggregate is limited to maximum 4.75mm beyond which it is known as coarse aggregates. Fineness modulus is only a numerical index of fineness that gives some idea about the mean size of the articles in the entire body of concrete.

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."
