Manufactured sand (MS) is widely considered as an alternative of the river sand (RS) recently, and to clarify the influence significance and influence mechanism of MS characteristic parameters on its concrete performance is essential to …

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 .

The following table indicates sand fineness modulus value ranges from 2.6 to 3.2. Fineness modulus with respect to various zones of sand according to IS 383-1970 are given in the table below.

This article discusses the properties of sand, fineness modulus, classification, and gradation curve of sand using the logarithmic graph.

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.

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.

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.

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 …

The fineness modulus of aggregate is simply a measurement of the average size of the aggregate. It can be calculated with the help of different sizes of the sieve. Now, let us see some numerical Examples to calculate the fineness modulus of aggregate.

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 …

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

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.

They showed that the Fineness Modulus of sand was among the principal factors affecting the workability, strength, durability, plastic viscosity, density and …

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 …

Generally, the larger the screen size is, the larger the fineness modulus of MS is and the lower the fines content is, and vice versa. Therefore, a screen size of 3.5–4.5 …

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.

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 …

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.

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 gradation and fineness modulus of machine-made sand are important factors affecting the performance of mortar. By studying the influence of different machine-made sand gradation and fineness modulus on the workability and rheological properties of mortar, the gradation and fineness of machine-made sand are explored.

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 …

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.

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 ...

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 …

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 ...

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.
