Hope it will consume less time in case of repetitive calculations. Excel Sheet For Sieve Analysis Of Aggregate And To Calculate Fineness Modulus- engineeringcivil
Dec 01, 2009· Sand that is too coarse (lower GFN) can create high permeability and lead to problems with metal penetration, rough surface finish, burn-in and burn-on. The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample.
The most coarser of all the samples is Sargodha crush as its fineness modulus is greater of all. As surface area is inversely proportional to fineness modulus so Chenab sand will be having the greater surface area of all the samples as its fineness modulus is least that is 1.492.
Fineness modulus (by weight) 3.03 fineness modulus (by volume) = 3.23 A fineness modulus of 3.23 by volume as shown in Table 3.1 indicates a considerably coarse grading than that normally associated with the fineness modulus of 3.03 by weight. Therefore, lightweight aggregates require a larger percentage of material
Engineering Classification of Shari Ghat River . Index Terms— River Bed Sand, Fineness Modulus (FM . Sieve Analysis of Sand Sieve analysis is . Get Price And Support Online; Fineness Modulus of Sand (Fine Aggregate) and sieve . Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand.
Jan 29, 2019· The fineness modulus of lightweight fine aggregates and sand were 4.4 and 2.2, respectively. On the other hand, the particles combined by using lightweight fine aggregates and sand exhibited continuous grading, which nearly satisfied the standard distribution curves of the ASTM C330 . The fineness modulus of the combined fine aggregates tended ...
Sep 01, 2014· 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. Fineness Modulus of Sand Why to Determine Fineness Modulus?
Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 10mm to 20mm. Limits of Fineness Modulus Fineness modulus of coarse aggregate varies from 5.5 to 8.0. And for all in aggregates or combined aggregates fineness modulus varies from 3.5 to 6.5.
The information obtained from fineness modulus is helpful in the following ways; Sieve Analysis. 1- Fineness modulus tells us directly whether the material is well-graded or gap-graded. 2- Fineness modulus gives us an overall idea whether the material is fine or coarse. Higher the value of FM,coarser will be the aggregate.
FINENESS MODULUS OF FINE AGGREGATE. FINENESS MODULUS OF FINE AGGREGATE TxDOT Designation: Tex-402-A Effective Date: August 1999 1. SCOPE 1.1 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete. 1.2 The values given in parentheses (if provided) are not standard and may not be .
absorption and fineness modulus of the river sand used . ... experiments were carried out to study the gradation of aggregates, workability, compressive strength and split tensile strength of ...
Nov 03, 2017· Then calculate the percentage of Wt of cement-retained on Sieve. Repeat the above experiment with three different samples of cement and average the values for accurate results. The fineness of Cement Formula:-A good cement should retain 10% wt of cement when it is sieved with the 90µm sieve. Also Read:-Initial and final setting time of cement
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. So, in the calculation of coarse aggregate we need ...
FINENESS MODULUS OF FINE AGGREGATE TXDOT DESIGNATION: TEX-402-A CONSTRUCTION DIVISION 2 – 2 LAST REVIEWED: SEPTEMBER 2014 4.2 Calculate the Fineness Modulus (FM): FM Cumulative percent retained= ( ) / 100 4.3 Table 1 lists example amounts for discussion purposes. Table 1—Amounts for Example Calculations
Feb 11, 2014· Since the volume of the saturated sand is the same as that of the dry sand, the saturated sand completely offsets the bulking effect. Note down the level of sand, say h 2. Subtract the final level h2 from initial level h1 (i.e. h 1-h 2), which shows the bulking of sand under test. Calculate percentage of bulking using formula given below.
Every laboratory situation is different. The lab should be set up to meet the flow requirements of the most routine test performed. The need for back-tracking should be minimized, especially if more than one technician is working at a time. A little extra time and thought to the set up of the lab
Importance of Sand Bulkage Test. If we need 1 m 3 of sand in concrete we need to know the approximate sand bulkage value. Say, for example, sample sand that we are going to use has 30% bulkage of sand then we need to take 30% more sand that is 1.3 times of sand while volume batching in order to get 1 m 3 of sand for concrete.
Fineness Modulus Fineness Modulus is de! ned as an index to the particle size not to the gradation. Fineness Modulus is calculated from the sieve analysis. It is de! ned mathematically as the sum of the cumulative percentages retained on the standard sieves divided by 100.
Automatic control of fineness modulus is the key technology in this process. Typical features are listed below in detail. 1. German sand producing host machines are equipped and of low energy consumption, low cost, good particle shape, and stable grading. The impact rotors in two cavities largely increase the crushing effect and reduce the ...
The object of this experiment is to determine the fineness modulus and hence to plot the particle size distribution curve for the sample of fine aggregate supplied. Theory The fineness modulus of a sample of aggregate is an index number which is roughly proportional to the average size of particle in the aggregate, that is, coarser the ...
