Air permeability specific surface - Wikipedia

The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder.

Has anyone used Blaine test to measure the fineness of .

The reference material is always the cement which the Blaine specific surface and density are knew. These parameters will be used to determine de K of your Blaine apparatus.

surface area in square metres of all the cement particles in one kilogram of cement. The higher the The higher the specific surface is, the finer cement will be.

FINENESS OF CEMENT BY BLAINES AIR PERMEABILITY METHOD

In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes). Now a day’s fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of the cement particles per unit mass.

FINENESS OF CEMENT BY BLAINES AIR PERMEABILITY METHOD . FINENESS OF CEMENT BY BLAINES AIR PERMEABILITY METHOD ISDetermination of the density of cement To determine the density or specificS = Specific surface area

3.7 - The fineness and particle size distribution of .

When the surface area of a cement is measured using gas sorption, a technique that measures how many gas molecules can fit on the surface of a solid, the resulting value is 2-3 times higher than the Blaine value . This occurs because the cement particles have a rough, irregular surface with internal cracks and pores.

Specific surface area =41048 x (PP^-0.394) x (n^-0.198) x (density^-1.078) Where PP is position parameter on RRSB Graph for given sample. n = RRSB Number or RRSB Slope. density = density of sample in g/cm3 (typically for cement = 3.15 g/cm3) Ex: For a typical cement sample which i have measured for a client was as follows. PP= 30.03 ; n = 1.16 ; density = 3.15 g/cm3. Calculated surface area .

HMK-C1 Cement Blaine Fineness Air Permeability Apparatus

HMK-C1 Blaine Apparatus is a cement testing apparatus used to determine the particle size of portland cement, limes and similar powders using the Blaine air-permeability method. It gives accurate and repeatable test results of cement specific surface area.

InstruQuest Inc.

cement fineness, porosity, and density using automatic gas pycnometer The purpose of this note is to present a more convenient approach to measurement of cement density, porosity, and fineness (specific surface area) using a specialized version of the HumiPyc series of gas

Factors Affecting the Density and Specific Surface Area .

In this study, the factors affecting the density and specific surface area (Blaine value) of coal fly ash were investigated on the basis of experimental results obtained using our combustion test facility and the ash data from the boiler of an actual electric power plant. The density was affected by the ash particle size, the true density of the component materials, and the aluminum content .
