Fine Aggregate Affect Concrete Mix Design Sigmatest

How fine aggregate affects concrete mix design. Fine aggregate testing is a concoction of various materials which are distributed, refined, and picked after going through thorough analysis through a sieve test. The aggregate must have the right proportion of course and fine agglomeration, for it to be considered fit for use in construction.

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

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."
