REFERENCE MATERIAL CEMENT
BLAINE APPARATUS 
SMR 1C

This reference material cement is used for the calibration of Blaine test

CONDITIONING

For each test, you need maximum 5 gr, so S.N.L proposes to do box of 20 bottles of 5 gr with a sealed with a secure screw cap. Physico-chemical properties of the sample are stable until the bottle is closed and the cap untouched.

 

The certificat of analysis Is produce by  l’ATILH paris la défense as following:

PARTICIPATION AND EXECUTION OF TESTS

Each year the “Association Technique de l’Industrie des Liants Hydrauliques” (ATILH) organises an interlaboratory test campaign involving in particular the participation of the cement production industry laboratories, the cement end-user laboratories and Research and Inspection Centers within the construction materials sector. This participation is compulsory for laboratories accredited by COFRAC for cement testing. The tests are carried out in accordance with standardised methods where latter exist, otherwise according to everyday traditional methods.

STATISTICAL ANALYSIS OF THE RESULTS

Outliers are eliminated via the STUDENT’s test with a confidence level of 98 %. A reiteration is set at this threshold in order to keep only those values which are related to the “Normal or Gaussian” distribution, the latter being entirely defined
by 2 parameters: mean and standard deviation. The coefficient of variation symbolised by “V” is the ratio between the standard deviation “σ” and the mean value X .

SPECIFIC SURFACE AND PARTICLE SIZE ANALYSIS

For the calibration of the Blaine permeability apparatus, follow the requirements of the EN 196-6 standard, paying particular attention to the temperature corrections, if any. To determine the volume of the compacted layer, it is not essential to use the Reference Material (but ensure that a sufficient quantity is taken so that the mass of the mercury does not modify the compaction of the powder layer). Reference Material should be used systematically:

  • after 1000 tests;
  • when using another type of manometric liquid, another type of filter paper, a new manometer tube or a new perforated disc;
  • If discrepancies are systematic with the secondary reference cement.
