The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process. The airjet sieving method measures the retention on sieving and is suitable for particles which substantially pass a 2,0 mm test sieve.

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.

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).
Standard methods of testing cement are essential adjunct to the cement specifications. This standard in different parts, lays down the test procedures to evaluate the physical properties of different types of hydraulic cement. This part covers determination of fineness by wet sieving.
