THE ROLE OF FINENESS MODULUS Southport Concrete Co

Jul 20, 2021 · Calculation Process Concrete workers calculate fineness modulus using sieves with progressively smaller holes. Separate sets of sieves are used for coarse and fine aggregates. The measuring process itself will be the same for both categories of aggregate. First, the sieves must be arranged in a stack in descending order.

Fineness Modulus

the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subdivided by 100 gives the value of coarse aggregate. Higher the aggregate size higher the Fineness modulus hence fineness modulus of coarse aggregate is higher than fine

Sieves mounted in frames larger than standard 8" diameter are used for testing coarse aggregate to reduce the possibility of overloading the sieves. When working with mixed materials that are coated, lumpy, or baked together, the material must be pulverized enough to separate the particles and remove the coating as much as possible.

Sieve analysis Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

Mar 27, 2021 · Fine and coarse aggregate generally occupies 60% to 75% of the concrete volume. Coarse aggregate is that which will not fit through a No. 4 (4.75mm) sieve; fine aggregate passes through the 9.5mm sieve and is completely retained at the No. 200 sieve. After the aggregate is sampled and the moisture content determined, the sample is weighed. It
