4.2. Based on Fineness Modulus The fineness modulus is also considered as the indication of quality of aggregate. According to IS recommendations the aggregate should posses the F.M to the range of 2.6 to 3.2. Greater than 3.2 should be rejected. The Classification of sand based on Fineness modulus is as follows, Fine Sand 2.2 to 2.6

Sometime it may happen that, the aggregate available at site is not conforming to the desired grading. In such case two or more aggregates from different sources may be combined to get the required grading. Fineness modulus value can be used as a technical way to blend coarse aggregate with fine aggregate to produce desired [.]

Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal penetration, rough surface finish, burn-in and burn-on. The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample. AFS ...

For aggregates used in PCC, another common gradation description for fine aggregate is the fineness modulus. It is described in ASTM C 125 and is a single number used to describe a gradation curve. It is defined as: The larger the fineness modulus, the more coarse the aggregate.

Författare: Er.Sathavara DineshGET PRICE >>What Is Fineness Modulus of Sand? 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 sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
