Oct 25, 2019· Sieve Analysis Of Aggregate And Fineness Modulus Calculation Spreadsheet The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with ...

FINENESS MODULUS (FM) - The fineness modulus (FM) is a factor obtained by adding the percentages of material in a sample of aggregate that is retained on each of the following sieves: #100, #50, #30, #16, #8, #4, 3/8", ¾", 1 ½", 3", 6". The result is divided by 100 to arrive at the fineness modulus. For conventional concrete the ...

Aug 11, 2018· In brief. The coarse aggregates are the material retained in the No.4 sieve (4.75mm). While the material passing through No.4 sieve (4.75mm) and retained in the No. 200 sieve (75μm) is considered as fine aggregate; and material passing No. 200 sie...

In order to determine the fineness modulus of a fine aggregate the accumulative percentage by weight retained on each of the test sieves Nos. 100, 52, 25, 14, 7, 3 /16 in., 3 /8 in. shall be calculated from the sieve analysis, in accordance with the method given in Appendix B. The percentages shall be added together, and the fineness modulus ...

Determination of Fineness Modulus of a Sample of Fine Aggregate Posted on January 20, 2020 April 8, 2020 Author admin Hello Friends, This is Mukesh from Learning Technology.

The fineness modulus of fine aggregate is 2.60and its specific gravity 2.58. The absolute density in kg/m 3 is 1000 times larger than the specific gravity. Procedure: After fixing the maximum size and type of aggregate, the workability is determined with the help of water content obtained from given tables 20.23 and 20.24, and bulk volume of ...

The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 6. Coarse aggregate volumes are based on oven-dry rodded weights obtained in accordance with ASTM C 29. Table 6: Volume of coarse aggregate per unit of volume of concrete. Maximum aggregate size, mm:

space is provided for entry of the sand fineness modulus (F.M.) which is obtained from the Regional Materials Engineer and the specific gravity (S.G.) of aggregates and cement. The aggregate S.G.'s are found in the current aggregate source book.

Increased Modulus of Elasticity. The 28-day compressive strength & modulus of elasticity of concrete, with or without entrained air, increases with an increase in cement fineness. The difference in compressive strength due to difference in fineness of cement is considerably less at 1 year's age. Increased Drying Shrinkage

The Fineness Modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100.Sieves sizes are: 150-μm (No. 100), 300-μm (No. 50), 600-μm (No. 30), 1.18-mm (No. 16), 2.36-mm (No. 8), 4.75-mm (No. 4), 9.5-mm (3/8-in.), 19.0-mm (3/4-in.), 37.5-mm (11/2-in.), and larger ...

Fineness modulus of sand = 2.20. Consider From Figure 2 using the specific gravity of coarse aggregates and the fineness modulus of sand then ; hence WD = 0.495 × 1.45/0.453 = 1.58. Assume for max. size of 20 mm. Then From Figure 4 using value, medium workability plot, and fineness modulus of 2.20, the will be 1.12. Also the value = .

3.2. Based on Fineness Modulus As per IS 1542: 1992 – clause 5.2, the fineness modulus of sand shall be not less than 1.4 in case of crushed stone sands and crushed gravel sand and not less than 1.5 in case of naturally occurring sands. Lower FM indicates fine sand and higher FM indicates courser sand. 4. Result interpretation 4.1.

Fineness Test of Cement. PROCEDURE OF FINENESS TEST OF CEMENT: Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as W1. Drop 100 gm of cement in 90 µm sieve and close it …

14.3.3 Fineness Modulus Fineness Modulus (FM) is used in determining the degree of uniformity of the aggregate gradation. It is an empirical number relating to the fineness of the aggregate. The higher the FM is, the coarser the aggregate is. Fineness Modulus is defined as the sum of the cumulative percentages retained on specified sieves
