The Blaine apparatus determines the fineness of cement, and of other powdery products, as a specific surface in cm²/g. The digital Automated BlaineGenPLUS is manufactured to EN 196-6, Methods of testing cement - Determination of fineness, and to ASTM C 204, Fineness of Hydraulic Cement by Air Permeability Method.
In the test, cement is compressed under the conditions the standard defines and a set quantity of air is drawn through the compacted powder. Resistance to air flow is directly proportional to the fineness of the grain, as long as the same testing conditions are respected throughout.
Specific surface is what a cement plant uses to control the uniformity of its milling process, and the same measurement is applied to the particle size of other powder materials. There is a fuller account of the method in our blog.

Automated BlaineGenPLUS.
The point of the automatic instrument is that the operator prepares the sample and the machine does the rest, including the parts of the manual method where human timing is the weakest link.
Automation covers calibration, the test itself and everything after it:
The screens below show a completed result, the constant calculation and the direct mass reading.
BlaineGenPLUS fulfils the validation requirements demanded of automatic methods for the determination of Blaine fineness, described in ASTM C 204-07, chapter 12.
Its accuracy and precision exceed the manual method, because the errors in the measurement of time are far lower. Calibration is carried out with a cement surface standard reference material, for example NIST 114q, and results are best when the test is run in a room with controlled temperature.
The optical sensor and the cell cap that make that timing possible.

The BlaineGenPLUS interface is built around simplicity: the buttons and menus are laid out for fast operation and quick access to every function, so an operator reaches the test without working through nested screens.
What comes in the standard configuration.

The Blaine apparatus must comply with AASHTO T153 and ASTM C204.
According to IS: 3031 (Part I), 1996, good quality cement must have a fineness value smaller than 10% of the weight of cement particles that are bigger than 90 microns.
For one, Portland cement is among the lowest-cost materials and most widely preferred for use over the past century. This is because the materials used to produce Portland cement including shales, limestone, and various other naturally occurring materials are cheap and widely available. the concrete produced by Portland cement is among the most versatile construction materials in the world.
A common type of cement for general use, Portland cement is the most widely-used basic ingredient in concrete, stucco, mortar, and non-specialty grout all over the world.
Both the automatic and semi-automatic Blaine apparatus versions offer better precision and more accuracy than those offered by the manual iteration of the Blaine apparatus. A cement sample reference like the NIST 114q is used to calibrate the unit. To get the most accurate results possible, the test must be done in an environment with a controlled temperature.
The air-permeability Blaine apparatus is primarily a means to draw a specific amount of air through a ready cement bed with definite porosity. It works by drawing in a specific amount of air through a cement bed with a definitive porosity measurement. The size and number of pores in a pre-set bed with an absolute porosity value. It is a particle size function and determines the airflow rate through the bed. The procedure is outlined as Method A in ASTM C204 and AASHTO T153.
Typically expressed in sq2 /g of surface area, there are 2 kinds of Blaine apparatus testing methods: test methods A and B. Test method A, the reference test method, involves the manual operation of the standard Blaine apparatus. On the other hand, Test method B allows using an automated apparatus that has proven the ability to come up with acceptable performance.
The fluid called MA13 Blaine Air Permeability Manometer is a non-mercury fluid indicator (red spirit) used together with the MA10 Blaine Air Permeability Apparatus to determine the Portland cement fineness. 8 oz or 240 ml bottles are available as refills. Features include its use for testing based on standards set by the ASTM and AASHTo.
A Blaine number is the surface area-based parameter that is quantified with the use of the air permeability method. The technique is well-established in the cement industry. However, it has several widely recognized and important limitations. These include 2 types of cement of the same Blaine number exhibiting different characteristics in terms of performance.
Measuring cement fineness involves filtering the material on standard strainers. This way, you determine the cement proportion where the grain size is bigger than the specified size of the mesh. The cement fineness measurement is expressed as a specific surface. A bigger specific surface means finer cement will be produced.
Determining the Portland cement fineness value involves using the Blaine Air Permeability Apparatus. It measures the particular fine materials' surface area in sq2 cm / g of the test sample. With the use of the apparatus, an amount of air is drawn via a bed with pre-defined porosity.
Measuring the fineness value of Portland cement involves the use of the Blaine Fineness Apparatus. The test is performed according to standards set by the AASHTO and ASTM. The fineness measurement is based on the specific cement area, which is expressed as the total surface area in cm2 / g (square centimeters per gram).
The average Blaine fineness value in modern cement varies anywhere between 3,000 and 5,000 cm2 / g (or 300 – 500 m2/kg). The company says that the vertical roller mills housed in the complex make achieving the maximum disintegration level possible by grinding down the material down to 4,500 - 6,000 Blaine fineness. This ensures the hardening rate and cement strength.
BlaineGen PLUS, Automatic Blaine Apparatus, perfectly meets the standard EN 196-6 and ASTM C 204. This essential, considering, most other systems do not comply with this criteria.
It is also important to note that the specimen dimensions are in accordance with the standard. The operator does not required to use bigger sample sizes than the standard bed of cement.
Accuracy and repeatability combined with exceptional user-friendly interface is what gives the end user the ultimate advantage with the Automatic Blaine system.
