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).
Model:DBT-127. Standards: GB 8074 and ASTM C204. The Blaine air permeability apparatus is used to determine the specific surface area and fineness of cement and other powder material according to the GB 8074 and ASTM C204 standards.
WHAT IS FINENESS OF CEMENT? Fineness of cement is property of cement that indicate particle size of cement and specific surface area. and indirectly effect heat of hydration. IMPORTANCE/EFFECT OF FINENESS OF CEMENT: 1. Fineness of cement affects h...
The below mentioned article will guide you about how to determine the fineness of cement. Determination of Fineness of Cement by Specific Surface by Blaine Air Permeability Method (as per IS 4031-1958): The determination of specific surface of cement is a recent development.
Jan 02, 2013· How does Blaine fineness relate to micron sizes – The Q&A wiki. Typically, higher numbers for Blaine Fineness relate to smaller particle size.Think of it as spheres, the smaller you make your sphere the more surface area there is . »More detailed
4. The air-void system in air-entrained concrete or concrete containing no entrained air is not significantly affected by variations in the fineness of cement. 5. The 28-day compressive strength of concrete, with or without entrained air, increases with an increase in cement fineness.

May 02, 2013· Before sieving, air set lumps of cement should be broken; Sieving should be done by rotating the sieve and not by translation. Technical Discussions. Fineness of cement has a great effect on the rate of hydration and hence the rate of gain of strength. Fineness of cement increases the rate of evolution of heat.
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.
It is truth that the Blaine surface area method is not the best to determine fineness of others powders materials than Portland cements. This method was developed to measure cement fineness and ...

Feb 14, 2017· 2 Date:27/01/2017 FINENESS OF CEMENT BY BLAINE'S AIR PERMEABILITY TEST Aim: To determine the fineness of cement by Blaine's air permeability test. Reference code: IS 4031-2 (1988) –Methods of physical tests for hydraulic cement and IS 12269 Specifications for OPC 53 grade.
1.1 This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: Test Method A is the Reference Test Method using the manually operated standard Blaine apparatus, .
3.7 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 3-7 below).
The air permeability specific surface of a powder material is a single-parameter 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 air-permeability test that indirectly measures the surface area of the cement particles per unit mass.
