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).
