This International Standard specifies a method to determine the fineness of iron ores in terms of specific surface area, using the manual Blaine air-permeability apparatus. This International Standard is applicable to pellet feeds in the range of 400 cm 2 /g to 2500 cm 2 /g of specific surface area.

06-04-2018· Blaine Air Permeability Apparatus. PROCEDURE: Put a filter paper into the cell then weight 2.84g of cement sample into it. Put another filter paper on it and compress with the plunger. Attach the cell on top of the U-tube manometer. Evacuate the air in the manometer through the side tube using the aspirator bulb until the oil reaches level 1.

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, …

In the instrument described below, air permeability method is used to determine the specific surface as a total surface area in cm2/g of material. Air Permeability Apparatus (Blaine …

When cement is manufactured the final process is the grinding of the clinker to form powder. The fineness of this powder is an important property. The finer the grinding the higher the specific surface. The Blaine of cement refers to the fineness ...

09-09-2020· So, if you have a large surface area and a small pressure, ... (let's use David Blaine plus other equipment with a mass of 100 kg) and divide by the lifting force for one balloon.

In most of the articles we use for creating our database, information about that for cement, silica fume, fly ash and other cementitious materials is given through BET surface of Blaine surface .

How to find the surface area of a cube. Recall that a cube has all edges the same length (See Cube definition). This means that each of the cube's six faces is a square. The total surface area is therefore six times the area of one face. Or as a formula: Where s is the length of any edge of the cube.

30-05-2018· Surface Area Formulas. S = ∫ 2πyds rotation about x −axis S = ∫ 2πxds rotation about y −axis. where, ds =√1+( dy dx)2 dx if y = f (x), a ≤ x ≤ b ds = √1 +( dx dy)2 dy if x = h(y), c ≤ y ≤ d. There are a couple of things to note about these formulas. First, notice that the variable in …

Use the calculator above to calculate height, radius or surface area of a cylinder. Enter any two values and the missing one will be calculated. For example: enter the radius and height, and press 'Calculate'. The surface area will be calculated. Similarly, if you enter the height and area, the radius needed to get that area will be calculated.

The Blaine Air Permeability Apparatus determines the fineness of Portland cement in terms of specific surface area expressed as the total surface area in square centimeters per gram of mortar or cement. The Blaine works by drawing a definite quantity of air …

BET theory can be applied to estimate the specific surface area of activated carbon from experimental data, demonstrating a large specific surface area, even around 3000 m 2 /g. However, this surface area is largely overestimated due to enhanced adsorption in micropores, [5] and more realistic methods should be used for its estimation, such as the subtracting pore effect (SPE) method.
