Fineness modulus of sand used in a concrete mixing plant

mixing of fine sand and cement

mixing cement sand and aggregate process - MC World. ... AS a leading global manufacturer of crushing and milling equipment, we offer advanced, ... These specifications do not specify any limit for fineness modulus to be used in concrete.

High strength concrete is used in multi storied buildings, bridges, bunkers, silos, atomic power plant. Current practice shows that for formulating HSC use of natural sand is common all over sites.

tap water (pH = 6.9) was used for both concrete mixing and curing purposes. Sulfonated naphthalene ... absorption and fineness modulus of the river sand used in this study were also determined ...

CHAPTER 2 SIEVE ANALYSIS AND FINENESS MODULUS Sampling

There are three principal aggregate sampling points that are of concern at a concrete plant. These are: 1) source of material, (quarry, gravel pit, etc.) 2) the stockpile, and 3) the storage bin. The ! rst two will be discussed in this section and the third in the section on moisture content and batch weight adjustments.

What is Fineness Modulus of Sand (Fine Aggregate) and …

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.

Effects of various fineness moduli of fine aggregate on engineering properties of high‐performance concrete

The sizes of coarse aggregate were 19 mm, 12.5 mm, 9.5 mm, 4.75 mm, 2.36 mm and 1.18 mm. Mixtures of local sand and Sylhet sand (1:1) and with fineness modulus of 1.93 was used as fine aggregate.

used jaw mobile crusher with excellent output fineness. fineness modulus of sand and Sand crushing plants Mobile fineness , fineness ... Influence of crusher dust on the properties of concrete Fineness modulus 2 76 ... or to reduce the size of a solid mix of materials as in rock ore, so that pieces of different composition can.

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 fineness modulus is computed by adding the cumulative percentages retained on the 6 in., 3 in., 1 1/2 in., 3/4 in., 3/8 in., No. 4, No. 8, No. 16, No. 30, No. 50, and No. 100 ...

Mass Concrete Mixtures Based on Fineness Modulus and ...

Ideal and optimum fineness moduli are used in combination with the geometrical gradation of aggregates to establish the mix proportioning of mass concrete. The ideal and optimum fineness moduli are experimentally determined for each maximum size of aggregate (MSA) by making concrete mixtures with aggregates of different fineness modulus and ...

For conventional concrete the fineness modulus of the fine aggregate should range from 2.3 to 3.1. ... For instance, sand with a low fineness modulus has more voids in it and more particle surface, thus, more paste is needed to fill voids and cement the particles ...

What will be the effect on concrete if we increase the sand quantity in concrete …

OPEN THE WINDOW Have a look at the following diagram. You can see that when you move from a regular mix to self compacting concrete - you are adding around 8% extra fines (dreaded in regular mix) which can be of any form ranging from supplementary...

Grading of Aggregate and Fineness Modulus of grading of aggregate

Therefore, fineness modulus cannot be used as a description of the grading of aggregate. When the use of the fineness modulus in the assessment of variations from the same source or parabolic behavior of a concrete mix is of great help. It reduces the ambiguity in the classification of fineness of sand.

The fineness modulus is computed by adding the cumulative percentages retained on the 6 in., 3 in., 1 ½ in., 3/4 in., 3/8 in., No. 4, No. 8, No. 16, No. 30, No. 50, and No. 100 sieves, and then dividing by 100. The fineness modulus of a fine aggregate is useful in estimating the proportions of fine and coarse aggregates in concrete mixtures ...

Study on the Fluidity and Strength Properties of High Performance Concrete Utilizing Crushed Sand …

In test results, fineness modulus of pure SS was 2.8 and it was suitable for using in concrete. However fineness modulus of pure CS was 3.98 and it was not suitable for concrete aggregate. In case of blended aggregate with CS of mixing ratio of below 50 %, its particle size distribution met the standard range even the fineness modulus was relatively high.
