Read MoreCement Cement Testing Britannica. Cement Cement Cement testing Various tests to which cements must conform are laid down in national cement specifications to control the fineness soundness setting time and strength of the cement These tests are described in turn below Fineness was long controlled by sieve tests but more sophisticated methods are now largely used
Read More1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300m No. 50 the 150m No. 100 and the 75m No. 200 sieves. 1.2 The values stated in either SI units or inch
Read MoreFineness test of cement procedure and Importance The Fineness test of cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose sie greater than 90 microns is determined and the percentage of retained cement particle are calculated. This is known as Fineness of cement
Read MoreThe number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement following number sieve is recommended by ASTM. Cement by wet process 300 sieve. Cement by dry process 200 sieve. Apparatus Sieve 200. Sample of cement. Triple beam balance. Brittle brush. Empty plate. Procedure
Read MoreFineness Test of Cement. To determine the fineness of cement by dry sieving as per IS 4031 Part 1 1996. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement the grain sies of which is larger than the specified mesh sie is thus determined. i 90m IS Sieve
Read MoreFineness Modulus of Cement by Dry Sieving The Fineness modulus of cement 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
Read MoreFINENESS MODULUS OF FINE AGGREGATE 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 exact Dry Weight of Original Sample 500.3 g
Read More6. Dry the sample again to a constant weight on a hot plate or in an oven at a temperature of 230176F 110 186C then accurately weigh and record. 7. Separate the sample into individual sies using the proper sieves. The sieves normally used are the standard 8 inch 200 mm sieves
Read More90 micron sieve is having aperture sie 90 micron. To determine fineness of cement 100 gram of cement is taken on sieve screen and sieving operation is done carefully without pressing cement
Read MoreIs not affected. Fineness also provides more cohesiveness to concrete and avoid separation of water at the top of concrete called bleeding. However increase in fineness of cement increases the drying shrinkage and cracking of the concrete. Fineness of cement is tested either by sieving or by determination of specific surface using air
Read MoreWhat Is Fineness Modulus of Sand Fineness modulus of sand fine aggregate is an index number which represents the mean sie 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

There are three method of checking fineness of cement. 1. By dry sieving as described above 2. Blaine air permeability method and 3. By wet sieving
Read MoreAug 08 2017nbsp018332There are different types of sieves such as 10 100 200 300 etc. the number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement the following sieve numbers are recommended by ASTM. Cement by wet process 300 sieve Cement by dry process 200 sieve 3
Read MoreFineness modulus is determined using percentages of the sie fractions from the sieve analysis and calculated for any designated series of sieve sies. When designing concrete mixes the FM of the fine aggregate is required for the effective proportioning of mixes
