Fineness modulus - Wikipedia, the free encyclopedia
Fineness modulus is a measurement of the coarseness or fineness of a given aggregate. For a fine aggregate, FM is calculated from the cumulative percentages of aggregate retained on sieves No.4, 8, 1...

The ideal and optimum fineness moduli are experimentally determined for each maximum size of aggregate (MSA) by making concrete mixtures with aggregates of different fineness modulus and determining which of the mixtures give the highest compressive strength for a given cement-to-aggregate ratio.

Blast-furnace slag is sometimes used to supply part of the ingredients. The raw materials are crushed and pulverized, mixed in proper proportions for the correct chemical composition, and fed into rotary kilns ... 8-11. The fineness modulus is an index of the relative fineness or coarseness of sand in a concrete mix.

The following describes the Standard Practice for Selecting Proportions for Normal, Heavyweight, and Mass concrete based on a report published by the American Concrete Institute (ACI), Committee 211. The Standard (ACI 211.1-91, Reapproved 2002) has been approved for use by agencies of the Department of Defense.
