The results show that there is a wide variation in the values of fineness modulus of different sands. Only two of the sands, i.e. S-6 and S-8 satisfy the ASTM fineness modulus criteria of 2.3 to 3.1 [12]. The rest of the 6 sands do not comply to ASTM criteria and are on the finer side having fineness modulus value ranging from 0.69 to 1.8. Fig. 1.

Mar 13, 2019 But in case of fully saturated sand the water films are broken and the volume becomes equal to that of dry sand. 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 80 mm to 150 micron and dividing this sum by 100.

The fineness modulus of a fine aggregate is defined as an index number that indicates the average or mean size of the sand particles. It is determined by carrying out the sieve analysis test using standard IS sieves. The fineness modulus is an estimate of the amount of aggregate required to proportion mix designs; it is not a precise …

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.

fineness modulus indicate that the aggregate is finer. It has been customarily used as a quality control measure of earth and reclaimed fill deposit. Relative density is only used on cohesionless soils, whereas compaction testing and proctors can be done on any soil.

This was explained by the fact that the crushing fine sand (CFS) used had a ... NF P18-101, NF P 18-540, NF P 18-598, fines content, the fineness modulus and the sand equivalent, and apparent and specific density. These results show that the fine fraction varied from 1.4% to 8.3% (the lower fine content was found for the river sand), while the ...

To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when we counted from lower-order sieve size to higher-order sieve.

To find the fineness modulus of fine aggregate we need sieve sizes of 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. 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 …

Abstract. Influences of nature Particle, size, grain shape and fineness modulus of fine aggregates on the 3D performance of cement-based mortar were investigated. Results showed that the working performance of the mortar is not only dependent on the fineness of the aggregate, but also the gradation and grain size of the …

Aggregates: two types of sand are used: dune sand (DS) with a granular extent of 0/1.25 with a fineness modulus of 2.1, quarry sand (QS) with a granular extent of 1.25/5 and a fi neness modulus ...

Concreting works require coarse sand with a modulus of 2.5 to 3.5 and the slit content must not be less than 4 percent. ... Manufactured Sand: Created by crushing hard granite stones, manufactured sand refers to an artificially created type of sand made as an alternative to river sand for construction. ... i.e. Fineness modulus (F.M.) = Sum …

Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm, 10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus is the number at which the average size of particle is known when …

than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus (FM) of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to 2.9 and 2.9 to 3.2 indicates that the sand is fine, medium and
