Ø There are two types to determine the fineness of cement: 1. Blain Air Permeability 2. Using Sieve # 100 and #200. Determination of Fineness of cement By Air Permeability Apparatus Objective: Determine Fineness of cement using Blain Air Permeability apparatus, in terms of specific surface "Total area per unit gram". Apparatus: • A balance
MA10 Blaine Air Permeability Apparatus for determining the fineness of Portland Cement measures the specific surface area of fine materials in square centimeters per gram of test sample. By using this apparatus, a quantity of air is drawn through a bed of definite porosity. The rate of air flow is determined by the pore volume in the bed, a function of the size of particles.
Fineness of cement is tested in two ways : (a) By sieving. (b) By determination of specific surface (total surface area of all the particles in one gram of cement) by airpermeability apparatus. Expressed as cm2/gm or m2/kg. Generally Blaine Air permeability apparatus is used. Apparatus : Test Sieve 90 microns, Balance, Gauging Trowel, Brush, etc.
2. Fineness of Cement: Regardless of composition, fineness is a vital property of cement, which influences the rate of reaction of cement with water. For a given weight of a finely ground cement, the surface area of the particles is greater than for a coarsely ground cement.
Fineness of cement is property of cement that indicate particle size of cement and specific surface area. and indirectly effect heat of hydration. Significance of the fineness of cement? * Fineness of cement affects hydration rate hence the rate o...
Blain Air Permeability Apparatus by EIE INSTRUMENTS The fineness of cement has a significant effect in its physical properties when used in concrete. Generally the finer the cement powder, the more rapid the concrete will set, as there is an i...
Blain Air Permeability Apparatus: MTCT03 The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a defined volume of air through a prepared bed of cement of defined porosity.

FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – principle of this is that we determine the proportion of ... View More Fineness Test on Cement | The Construction Civil
Jun 25, 2013· How to Read a Cement Mill Certificate: Part 1. ... Blaine fineness. Along with chemical reactivity of the cement composition, cement fineness controls early strength development. ... the important point is that a change in cement fineness signals a potential change in concrete performance and needs to be understood. The best place to start is ...
The fineness of cement is tested by measuring the air permeability specific surface area of the cement powder. The measurement of fineness of hydraulic cement is undertaken with the Blaine airpermeability apparatus to determine the specific surface expressed as the total surface area in square centimetres per gram (or square meters per kilogram).
Fineness is measure using a 90mm sieve or Blaine's airpermeability apparatus is also used. It measure the fineness in terms of specific surface. According to the IS 12269 OPC should have a value above 225m^2/kg and for PPC it should be above 300m^2/kg.
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").
Jan 01, 2013· 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 centimeters per gram or square meters per kilogram of cement.
