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.
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.
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.

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).
The appropriate sieving method depends on the degree of fineness of the sample material (fig. 1). Dry sieving is the preferred method for the size range between 40 µm and 125 mm. However, the measurement range is limited by properties of the sample such as a tendency to agglomerate, density or electrostatic charging. Vibratory Sieving
