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
Fineness, or particle size of portland cement affects rate of hydration, which is responsible for the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume ratio, which means more area available for water-cement reaction per unit volume. Approximately 95% of cement particles are smaller than 45 micron with the average particle size about 15 micron

For cement to be of normal consistence the penetration should be 10 mm according to ASTM standard on room temperature. If it's not so then the water and cement ratio will not be standard. Procedure for Initial Setting Time Test: For determining the initial setting time of cement paste, set the 1mm. diameter needle on the lower end of the rod.

How to Check Quality of cement on Site Fineness test of Cement:-As per IS: 4031 (Part 1) – 1996. The cement of good quality should have less than 10% of wt of cement particles larger than 90 m. (micron) To determine the number of cement particles larger than 90 m. or Fineness test of cement. The following apparatus is used.
A concrete mix of 1:2:4 (cement: sand: stone chips) by volume may be used for cement concrete paving blocks with water to cement ratio of 0.62. The concrete mix should not be richer than 1:6 by volume of cement to combined aggregates before mixing. Fineness modules of combined aggregates should be in the range of 3.6 to 4.0.
