  • AUTOBLAINE PREMIUM for automatic blaine tests of cements

    AUTOBLAINE PREMIUM: automatic apparatus for determining the specific surface area of cement (in cm2/g) according to the Blaine permeability method.

    The IBERTEST AUTOBLAINE PREMIUM equipment automatically runs the test to determine the specific surface of the cement by Blaine permeability method, even the sample weighing process, under the following testing standards:

    • EN 196-6: “Methods of Testing Cement. Determination of fineness “.
    • ASTM C-204: “Fineness of Hydraulic Cement by Air Permeametry Method”.

    Determining the specific surface area by Blaine method is done primarily to control the uniformity of the milling process in cement factories, but also is applied to other powdery materials such as slag or fly ash.

    Product Description

    Fundamentals of the Blaine test

    In the Blaine permeability test, an amount of cement is introduced into a cylindrical cell, where it is compressed to a fixed volume, then passing a defined volume of air through the compacted cement.

    The resistance to this air flow is inversely proportional to particle size, the larger the particles more gaps are created through which air can flow. Therefore, a finer cement exerts more resistance to air flow than a course cement. Through an experimental formula (Blaine method) can make an estimate of the surface area, which will be greater the finer the cement is.

    Advantages of IBERTEST AUTOBLAINE PREMIUM for the Blaine permeability tests of cements.

    The results of the IBERTEST AUTOBLAINE Premium equipment surpass those of the manual method in accuracy, precision and repeatability, since the errors in time measurements are much lower. The reading resolution of the flow time is 0.01 s (100 times better than that required by the standard).

    AUTOBLAINE PREMIUM equipment meets the validation requirements of automatic methods for the determination of Blaine fineness, and described in the ASTM C 204-07 standard, chapter 12

    The equipment should be verified using a standard cement of known specific surface, such as NIST standard cement. To obtain optimal results the test should be carried out in a room with controlled temperature.

    Advantages of the AUTOBLAINE PREMIUM for users and laboratories of testing cements, mortars and other materials.

    The operation of the AUTOBLAINE PREMIUM is completely automatic in terms of:

    • Integration with analytical balance that offers a direct measurement of the mass in the equipment, as well as the automatic calculation of the difference between the necessary weight calculated by the equipment and the current one.
    • Ergonomic display of tests and their results on screen.
    • Very intuitive renewed interface using a 7 ”resistive touch screen with IP65 waterproofing protection.
    • Device validation, the equipment meets the validation requirements for automatic methods for the determination of Blaine fineness (ASTM C204 standard).
    • Greater accuracy and precision, compared to the manual method, since errors in time measurements are much lower.
    • Greater repeatability in the obtained results, by eliminating the measurement uncertainty due to the human factor.
    • 2 Access levels, user and administrator (password protected).
    • Removable drawer for storage of accessories and consumables.

    The AUTOBLAINE PREMIUM device incorporates a renewed interface which which provides the user an improved
    experience in terms of:

    • Simplicity and intuitivity, thanks to the new design of the buttons and menus

      Results screen AutoBlaine Premium

      which provides the user a faster operation and quick access to all functions.

    • Modern design, ergonomic and attractive.
    • Display of menus and results, thanks to the new 7” screen with dust and splash resistance.

    On-screen assistant for conducting tests, including specific protocols for conducting the test according to EN 196-6 or ASTM C 204.

    Calibration screen in Autoblaine Premium

    The wizard shows the weight of cement to introduce into the cell depending on the density, desired porosity and selected Blaine cell. In case of purchasing the equipment with the communication option with the balance, the equipment will help during the weighing process, controlling the balance and displaying the remaining weight on the screen.

    Direct reading of the mass provided by the analytical balance

    For calibration it is recommended to use a primary standard, such as the Standard Reference Material (Portland cement with certified specific surface), but other standards from the laboratory can be used. The equipment stores the data of up to 5 different standard cements.

    The equipment temperature probe is also adjustable (by password) to calibrate with respect to a certified external thermometer.

    Up to 20 different types of cement can be entered and specific calculations can be made for each of them, varying parameters such as density, porosity of the compacted layer, etc.

    Up to 5 permeability cells can be registered, assigning a name for their identification and indicating the volume (in cm3) of the compacted cement layer. This data is obtained by calibrating the cell according to the method indicated in the standard or using the value indicated in the verification certificate.

    IBERTEST has permeability cells verified according to the standard. Likewise, we offer you our permeability cell re-calibration service.

    The equipment has internal memory to store up to 1000 tests.

    The complete tests stored in the memory of the equipment can be exported, through a USB 2.0 connection, to a computer, where they can be analyzed using the Microsoft Excel program.
