Fineness Modulus of Sand for Concrete Fineness of fine aggregate is related to term fineness modulus ; most commonly sand. Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete .

Modulus of fineness The basis of modulus of fineness is the same as the modulus of uniformity and the following example illustrates how it may be found and expressed. The selection of the method used to describe the size of particles will depend upon the use, which will be made of the information.

gradations can be used without a measurable effect on compressive strength. Fineness Modulus The fineness modulus is an indicator of the fineness of an aggregate and is most used for evaluating fine aggregates. The higher the number, the coarser the aggregate. The .

[PDF]Following test was conducted in site. Fineness modulus defines the size of the aggregates on concrete mix design. There are some limits on it though. If you have high modulus of fineness, the tendency of mixture is to have less pores as possible .The less pores you have, the good is .

The use of fly ash in limited amounts as a replacement for cement or as an addition to cement requires a little more water for the same slump because of fineness of the fly ash. It is generally agreed that the use of fly ash, particularly as an admixture rather than as a .

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.

The modulus of elasticity of concrete determined by sonic methods decreases as the fineness of the cement increases. 7. The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased.

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 [.]

[PDF]Aug 15, 2017 · Bleeding of Concrete: Causes, Effect and Ways to Reduce it Concrete is a mixture of cement, fine aggregates and course aggregates. Number of problems can occur in concrete due to improper mixing, curing and placing, one such problem is "bleeding" in concrete.

The effects of various fineness moduli (FM) of fine aggregate on the engineering properties of high‐performance concrete (HPC) were studied. Two kinds of coarse aggregates (stiff and soft) and three kinds of fine aggregates (FM=3.24, 2.73 and 2.18) were used.

The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1).

Effect of Fineness of Sand on Compressive Strength of Concrete. On the other hand by increasing Fineness Modulus from 2.5 to 3, Compressive strength increases from 49.00 to 56.83 MPa resulting in 16% increase in strength. For Every 0.1 increase in FM of sand from 2.0 to 3.0, 28 days Compressive Strength increases by 2.5 to 3.0%.

[PDF]fineness of modulus (2.3, 2.5, 2.7, 2.9, 3.1) to evaluate the SCC fresh properties [opt]. As per EFNARC (2002) [31], minimum coarse aggregate content of 28% was maintained for all the mixes. Keeping in view of the savings in cost and various global polluting effects, fresh, mechanical and

[PDF]Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by .

• The fineness modulus of the fine aggregate is required for mix design since sand gradation has the largest effect on workability. A fine sand (low FM) has much higher effect paste requirements for good workability. • The FM of the coarse aggregate is not required for mix design purposes.

Fineness modulus is a measure to define fineness of aggregate precisely it defines ... fineness modulus of sand - Newest Crusher, Grinding Mill ... Effect of Fineness of Sand on the Cost and Properties of Concrete . As fineness modulus of sand changes from 2.0 to 2.5 there is an increase in compressive strength ...

The fineness modulus of sand differs for each sand quarry. The purpose of this research is to analyze the effect of fineness modulus of fine aggregate (sand) on concrete compressive strength. The sand quarry taken in this study are from three sand quarry in Aceh Tamiang District. They are Johar quarry, Tanjung Karang quarry, and Alur Bamban quarry.

[PDF]effect of fineness modulus of sand on concrete mix. As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant. We also supply individual crushers and mills as well as spare parts of them.

In this study, the effects of aggregate gradation on the complex modulus function of asphalt concrete are determined. The two distinct properties of the aggregate blend considered in this study are the fineness modulus and the uniformity coefficient.

Fineness Modulus Method of Concrete Mix Design. The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM). Fineness modulus is determined separately by sieving coarse and fine aggregates through the following set of sieve.

Jul 08, 2017 · Effect of Fineness Modulus of Manufactured Sand on Mechanical Properties of Self Compacting Concrete 1.

Test methods for the water-cement ratio and fineness modulus). 1919 – Effect of Curing Condition on Wear and Strength of Concrete (Describing 120 tests on cylinder-shaped samples and 300 tests on cubic samples in various moisture conditions and testing periods varying from 3 days to 4 months).

The resulting value, called the Blaine fineness, is today expressed in units of m 2 /kg, although in previous times it was expressed in cm 2 /g. The Blaine fineness of OPC usually ranges from 300 – 500 m 2 /kg (3000 – 5000 cm 2 /g).

Fineness modulus = 283 ÷ 100 = 2.83 Table 1 - Fineness modulus (FM) is calculated by totaling the percent retained between the No. 100 and No. 4 sieve divided by 100.

[PDF]Abstract The effects of various fineness moduli (FM) of fine aggregate on the engineering properties of high‐performance concrete (HPC) were studied. Two kinds of coarse aggregates (stiff and soft) and three kinds of fine aggregates (FM=3.24, 2.73 and 2.18) were used. The results indicate that the slump and flowability for all fresh concrete in this study right after mixing are between 265 ...

[PDF]Fineness modulus is a measure to define fineness of aggregate precisely it defines coarseness or fineness of aggregate to be used in concrete. This can be defined as value that is derived by following expression: F.M = (cumulative percentage retaining of aggregate)/100.

Fineness Modulus (FM) of concrete aggregates is an empirical figure representing the mean particle size of an aggregate sample. The number is required in the selection of proportions for the concrete mix design process, but its real influence is not always understood by users.

The larger the fineness modulus is, the coarser the sand will be. The appropriate range of fineness modulus of the sand aggregate used in normal concrete is 3.7–1.6. Both medium sand and coarse sand spiked with some fine sand (coarse:fine = 4:1) are applicable.

In 1925, Duff Abrams introduced the concept of fineness modulus (FM) for estimating the proportions of fine and course aggregates in concrete mixtures. The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength."
