Aug 08, 2017· There 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.
The size of the particles of the cement is its fineness.The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process.As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.
Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method (Blaine Method).
This test is determine the fineness of cement samples by dry sieving. Fineness of cement Fineness of Cement. It is the measure of total surface area of cement.For finer cements,surface area will be more.Fineness influences the rate of hydration, rate of strength, rate of strength development, shrinkage, cracking, bleeding and also the cost of cement.
To Determine The Fineness Of Cement By Dry Sieving Theory: Cement is obtained by granding the various row material. The degree to which the cement is drawn to smaller and smaller particals is called fineness of cement. Finer the cement higher the rate of radiation and do faster the development of strain. This is because finer cement .
This test method covers hydraulic cement fineness tests performed using a sieve. The sieve frame should be made of a circular metal matching the specified dimensions, fitted with either a stainless steel woven-wire sieve cloth or an electroformed forced nickel sieve sheet. Both the nozzle and sieve shall not be subjected to corrosion by water.

Procedure to determine fineness of cement by dry sieving method: Take the 100 gm of cement sample given using balance as initial weight as W1 gm. Take 90 micron IS sieve and keep pan at bottom. Place the measured 100 gm cement sample on 90 micron sieve and break the visible lumps present in cement using figures without pressing it on 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 1.6 APPARATUS: Sieve # 200 Sample of cement Triple beam balance Brittle brush Empty plate 1.7 PROCEDURE: Take the triple beam balance and adjust the reading of the balance to zero.

Importance of fineness modulus Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Importance of fineness modulus, quarry, aggregate, and different kinds of minerals.
To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996. Principle. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) 90μm IS Sieve.
Free online knowledge for the paving industry. Fineness, or particle size of portland cement affects hydration rate and thus the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume ratio, and thus, the more area available for water-cement interaction per unit volume.
Fineness Modulus of Cement by Dry Sieving Home / Building Technology Guide / Fineness 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.

FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
5. Check the sieve after every 100 sieving as per para 4.4.2 of IS: 4031 (Part 1) 5. Observation 1. The fineness of a given sample of cement is _ _ _ _ % 2. Report the value of R, to the nearest 0.1 percent, as the residue on the 90 micron sieve for the cement tested.
Methods of finding fineness of cement: Fineness of cement is found by two methods A) By method of dry sieving B) By specific surface method- finding fineness of cement using Blanine's air permeability apparatus. Though method B is more accurate it is rarely used for specific purpose.Method A is quite good for field work.
