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).

Nov 03, 2017· 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 µm. (micron) To determine the number of cement particles larger than 90 µm. or Fineness test of cement. The following apparatus is used.
The fineness and particle size distribution of Portland cement. The final step in the production of cement is to grind the clinker pellets (and added gypsum) into a fine powder. The resulting individual cement particles have a variety of angular shapes, and a wide range of sizes (see Figure 37 below).

The Fineness Blaine Air Apparatus is used to determine the particle size of Portland cement, limes and similar powders expressed in terms of their specific surface. It comprises of a stainless steel cell, perforated disc, and plunger. A Utube glass manometer is .
The air permeability specific surface of a powder material is a singleparameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 ·kg −1 ("mass specific surface") or m 2 ·m −3 ("volume specific surface").
Jun 18, 2014· In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes). Now a day''s fineness is usually measured by the Blaine airpermeability test that indirectly measures the surface area of the cement particles per unit mass.
4. The airvoid system in airentrained concrete or concrete containing no entrained air is not significantly affected by variations in the fineness of cement. 5. The 28day compressive strength of concrete, with or without entrained air, increases with an increase in cement fineness.
The Blaine Fineness method covers the determination of the fineness of hydraulic cement, using the Blaine Air Permeability apparatus. The apparatus is available in a number of configurations including standard, semiautomatic, PCcontrolled and Dyckerhoff.
