There are many studies on numerous sand properties but there aren't many studies relating relative density and fineness modulus of sand. The aim of this research is to carry out an experimental study regarding the relation between the density and fineness modulus of sand and to establish empirical relation between them.
Types of Sand & Classification of Sand. Followings are the classification of Sand: Based on the grain size of the particle, sand is classified as Fine Sand(0.075 to 0.425mm), Medium Sand(0.425 to 2mm), and Coarse Sand(2.0 mm to 4.75mm) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.
3.5 Fineness Modulus and Gradation Parameters Relations. Analysis of the limited number of data of fineness modulus and gradation parameters yielded the following equations for the relationship between fineness modulus and gradation parameter for uniform gradation of sand samples.
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 …
Range of Values 3.1 The same value of fineness modulus may be obtained from several different particle-size distributions. In general a small value indicated a ... use fineness modulus variation as a convenient means of keeping quality history data on uniformity of particle-size distribution of aggregate production, delivery, and use. Some
The larger the sieve size, the greater the fineness modulus of the MS. The content of particles above 2.36 mm in the grading also increases. Practice has proved that when the smallest sieve mesh size is 3.5 mm, the fineness modulus of the produced sand is generally within 3.4, and the grading meets the standard requirements .
2.1.1 JVuttrral Sand - Fine aggregate resulting from the natural disinteg- ration of rock and which has been deposited by streams or glacial agencies. 2.1.2 Crushed Stone Sand - Fine aggregate produced by crushing hard stone. 2.1.3 Crushed Grace1 Sand - line aggregate produced by crushing natural gravel. .
Concrete is a buildings material made from a mixture of cement, sand, broken stone or gravel, and water. The fineness modulus is one of the physical properties of fine aggregates (sand). The Fineness Modulus (FM) of fine aggregates (sand) is an empirical figure obtained by adding the total percentage of the sample of a sand retained on each …
The fineness modulus(FM) represents the level of particle size of manufactured sand. Real-time feedback of FM of manufactured sand is important for in…
Gradation meeting the ASTM specifications, lowest percentage of micro fines and within range fineness modulus of S-8 sand are the supporting factors for the highest compressive strength. The trend of gradation of different sands as compared with the ASTM gradation limits is also confirmed by the results of the compressive strength. The S-2, S …
Manufactured sand can be adjusted by modifying the sand-making parameters. This involves controlling the fineness modulus, grain shape, and particle grading of the manufactured sand. Manufactured sand presents significant advantages, as supported by several studies and engineering examples.

Fineness Modulus of Fine Aggregate Fine aggregate (sand) grading affects consistence and finishability. Fineness Modulus (FM) is an empirical calculation used to support the optimisation of a concrete mix design.
Fineness modulus of sand is a parameter to find the sand quality. Read on for the meaning, use, calculation formula and importance of Fineness modulus of sand.
The main characteristics of MS are as follows: At present, it is medium-coarse sand with a rough surface and sharp edges, with fineness modulus between 2.6 and 3.6 and containing a certain amount of fines.
Higher the aggregate size higher the Fineness modulus hence fineness modulus of coarse aggregate is higher than fine aggregate. Coarse aggregate means the aggregate which is retained on 4.75mm ...
The effect of sands with different fineness modulus of 2.3, 2.5, 2.7, 2.9 and 3.1 on the fresh properties of concrete was studied, and the best results were obtained in the sand with the fineness ...
Explanation: 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 microns and dividing this sum by 100.. Fineness modulus of coarse aggregate is 6 - 8.5. Fineness modulus of fine aggregate is 2 - 3.5. The fineness modulus of different …
If in a concrete mix the fineness modulus of coarse aggregate is 7.6, the fineness modulus of fine aggregate is 2.8 and the economical value of the fineness modulus of combined aggregate is 6.4, then the proportion of fine aggregate is
Table 3 show that increasing proportion of sand causes a decrease the fineness modulus of combined aggregate. This shows average size of combined aggregate is getting smaller. If fineness modulus of combined aggregate smaller than 5.0435, the proportion of sand is greater than crushed stone.
We found that when the fineness modulus is in the range of 2.8–3.3, the change of grading and fineness modulus has little effect on the strength, which is less than 5%, as shown in Tables 4.19 and 4.20. This fact shows that the strength difference of mortar prepared by MS with the same fines content but different grading and fineness …
Fineness modulus of aggregate is an index number which gives an idea about the finance of aggregate and is an approximate proportion of the average size of particle in the aggregate.
Sand's fineness modulus refers to the mean size of its particles. There is remarkable success in predicting various fruits images, grains, vegetables, and soils using convolutional neural networks.
The fineness modulus of MS should be controlled between 3.0 and 3.4. If the fineness modulus is more than 3.5, there are too many coarse particles and too few particles smaller than 300 μm, so the grading is unreasonable, which induces worse workability of concrete. If the fineness modulus is less than 3.0, there is too much fine …

Explanation: Fineness modulus of sand (fine aggregate) is an index number that represents the mean size of the particles in sand.. FM is the sum of the total percentages retained on each specified sieve divided by 100.
In the investigations assessing the impact of the Fineness Modulus (FM) of manufactured sand on fresh SCC properties, an increase in the sand FM from 2.3 to 2.7 yielded improved results in slump flow, T50, L-box, and V-funnel tests. However, raising it to 3.1 resulted in the opposite outcome [41]. Similarly, in conventional concrete, an ...
