The fineness of cement is measured by sieving it on standard sieves. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. 12.2.2 Air Permeability Method ( Blaine Method ) The fineness of cement is measured as specific surface. Specific surface is expressed as the total%PDF-1.4 %âãÏÓ 4 0 obj /CA 1.0 /OP false /SMask /None /SA true /ca 1.0 /OPM 0 /op false /AIS false /BM /Normal /Type /ExtGState >> endobj 7 0 obj /N 4 /Filter /FlateDecode /Length 389757 >> stream H‰””uTÔK Ç tKˆ”ˆKJI, ‚t(Ý‹ »4ì KÇÒÝ%Ò¹´H—4J#‚Ò’ ‚(H w¹÷þqÏyïyßó~Ï3çùÌ™gÎ3óÌ„ Y 9El @¸ ]äÕ!OÔÌ-@ ã Àà \€ˆ¹¥+BVKK Àè: ø O X× . Blaine's air permeability apparatus follows a means of drawing a definite quantity of air through a prepared bed of cement of definite porosity. The basic principle used in the air permeability test to determine the fineness of cement is based on the relationship between the fineness of cement particles and the rate at which air can pass . 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 .
Sieve shown in pic below is not the actual 90µm seive.Its just for reference. Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest 0.01g and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.The Blaine Fineness method covers the 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. Two test methods are given: test method A is the reference test method .
The fineness test is an essential aspect of testing, as it helps determine the fineness of cement using two methods: the sieve test and Blaine’s air permeability test. The sieve test entails assessing the quantity of residual material on the sieve after consistent circular and vertical motion and circular motion for 15 minutes, with the . 1. Blaine air permeability test of cement. 2. Wagner’s turbidimeter test. 3. Particle size distribution method. 4. Lea & nurses air permeability test of cement. Blaine air permeability test of cement. Aim: To determine the fineness of cement by determining specific surface by Blaine’s air permeability method (IS 4031 – 1958). Air Permeability Method (Blaine Method). However, in this article, we’ll only discuss about the sieving method of determining the Fineness of Cement. Because this is the most common and easiest method to test fineness of cement.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-permeability apparatus. Expressed as cm2/gm or m2/kg. Generally Blaine Air permeability apparatus is used. 2 .

The Blaine Air Permeability Apparatus includes all of the items needed to determine the fines of Portland cement.. Blaine air permeability is a widely used test method in cement testing to measure the fineness or particle size distribution of .
Fineness of is cement expressed in terms of total surface area of unit weight of of cement. Tests 1) Sieve analysis ----->I.S.sieve NO.9 is used to test----->permissible limit for OPC is not more than 10% retained on .
Method of testing fineness of cement: a) Sieve Analysis Method. b) Air Permeability Method. For Sieve Analysis Method: The 100 grams of cement with an accuracy of 0.1 g is weighed as a sample and if any air-set lumps present in the sample are broken with the finger. The sample is placed on a 90-micron sieve and continuously sieved for 15 minutes.This apparatus determines fineness of Portland cement in terms of specific surface expressed as total surface area in square centimeters per gram of cement. .
