There are several methods that can be used to test the fineness of cement, including sieve analysis, air permeability, and X-ray diffraction. The most common test method is sieve analysis, which involves passing the cement powder through a series of sieves to pinpoint the particle size distribution.

The cement bed in the permeability cell is 2.5 cm in diameter and 1 cm depth knowing the density of cement the weight required to make a cement bed of porosity of 0.475 can be calculated. This quantity of cement is placed in the permeability cell. Now the air is passed through the cement bed at a constant velocity.The Blaine Air Permeability Apparatus is specifically designed to measure the fineness of Portland cement and other fine materials.. The apparatus consists of a stainless steel test cell with a calibrated U-tube manometer, a rubber aspirator bulb, and various components such as a filter paper, perforated disc, and ground glass joint.Fig. 1: Specific Surface versus Compressive Strength of Cement. 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 air .

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. This test is rarely used for fineness. Air Permeability Test: Blaine's Air Permeability Test is used to find the specific surface, which is expressed as the total surface area in sq.cm/g. of cement. The surface area is more for finer particles. Consistency test on cement. This test is conducted to find the setting times of cement using a . This post is written for civil engineering students and laboratory engineers. The reference IS 4031 (Part-1): 1996 is used in this post.

A number in parentheses indicates the year of last . We would like to show you a description here but the site won’t allow us.

Blaine Air Permeability Apparatus determines the fineness of Portland Cement by measuring the specific surface area of fine materials in square centimeters per gram of test sample. A quantity of air is drawn through a bed of definite porosity, and the rate of airflow is determined by the pore volume in the bed, a function of the size of particles. So, in the laboratory we can determine it by using tests methods of sieving and air-permeability apparatus. Fineness of cement. It is important to note that in common cement types, the smallest particle is of size 1.5 micron while the average size is about 10 micron.Now, in commercial cement about 30% of the particles are in size less than 7 microns.
