Fineness 10 Specific Surface Area Conversion

BET theory

BET theory. Brunauer–Emmett–Teller ( BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of materials. The observations are very often referred to as physical adsorption or physisorption.

The Fineness And Specific Surface Area Of Refractory Bricks

The ideal non-porous raw material has only the external surface area; but the raw material with pores has an internal surface area in addition to the surface area. There are many methods for measuring the specific surface area, such as gas adsorption method, organic molecule adsorption method and gas permeation method.

Specific surface area

Specific surface area (SSA) is a property of solids defined as the total surface area of a material per unit of mass, (with units of m 2 /kg or m 2 /g) or solid or bulk volume (units of m 2 /m 3 or m −1 ). It is a physical value that can be used to determine the …

Fibre strength and fibre fineness

 · • The specific surface area which determines the flow of air through a cotton plug, is dependent not only upon the linear density of the fibres in the sample but also upon their maturity. • Hence the micronaire readings have to be treated with caution particularly when testing samples varying widely in maturity.

What is Fineness Modulus of Sand (Fine Aggregate) and …

Calculation of Fineness Modulus of Sand. Let us say the dry weight of sample = 1000gm After sieve analysis the values appeared are tabulated below. Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd ...
