fineness modulus of river sand in south africa

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand It is calculated by performing sieve analysis with standard siev The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus Fineness Modulus Of River Sand In South Africa - cz-eueu Fineness Modulus Of River Sand In ....

Fineness Modulus

To find the fineness modulus of fine aggregate we need sieve sizes of 475mm, 236mm, 118mm, 06mm, 03mm and 015mm Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate Determination of Fineness Modulus of Sand To determine the fineness modulus, we need standard sieves, mechanical sieve shaker (optional ....

River sand 2507 Quarry dust 2688 Coarse aggregate 2703 323 Fineness Modulus Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 475mm to 150 microns and dividing the sum by an arbitrary number 100 The larger the value, the coarser is the ....

Fineness modulus

The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100Sieves sizes are: 150-μm (No 100), 300-μm (No 50), 600-μm (No 30), 118-mm (No 16), 236-mm (No 8), 475-mm (No 4), 95-mm (3/8-in), 190-mm (3/4-in), 375-mm (11/2-in), and larger ....

Fineness Modulus

It should be reminded that the fineness modulus can not reflect the quality of their grading regions The sand with the same fineness modulus can have very different grading regions Therefore, the particle gradation and the fineness modulus should be considered in the preparation of concrete...

The optimal grain fineness number (GFN) in a sand system is determined by the type of metal poured, pouring temperatures, casting product mix (heavy vs light castings) and required surface finish Once that optimal fineness level is determined, maintaining a consistent grain structure becomes a critical factor in the quality of the final castings Sand that is too fine (higher GFN) can create ....

Fineness modulus is an index no Which Indicates mean particle size in sand(fine aggregate) FM is obtained by adding cumulative percentage retained(percentage ....

Concrete Mix Design

A comparison of three maximum size gradings of sand-gravel and sand-crushed stone mixtures in concrete has revealed that for each type and size of coarse aggregate a constant value for fineness modulus will be obtained for any workable mixture from lean to rich, if the cement is included in the modulus figur While trial batches are still ....
