Portland cement SN1 / SN2 / SN3
CEMENT FAMILY: STANDARD CEMENTS
Based on European inter-laboratory tests under the aegis of the ATILH office, SNL offers you a set of standard cements for Blaine-meter, portlands cements, composite portland cements, Alumina.
In addition, we offer a SN2 Resi standard cement to test and validate the correct methodology of the CEN EN 196-1 standard.
We can offer you NIST or CCRL or Cement-NCBM equivalent
Reference materials – Portland cement SN1 / SN2 / SN3
REFERENCE MATERIALS CEMENT PORTLAND SN1 / SN2 / SN3
Standard reference Portland cement:-
Participation and performance of tests
Inter-laboratory test campaigns, organized by ATILH or SNL, enabled the constitution of reference materials.
European laboratories from the cement industry, cement users and research and control centers in the field of construction materials took part in these campaigns.
The materials analyzed are powders, cements and alumina. The physical and chemical properties measured are:
This standard cement allows the calibration of laboratory cement blainemeters.
Static analysis
The elimination of outliers is performed at the 98% level by the STUDENT test. A reiteration is fixed at this threshold, in order to keep only the values attached to the “Normal or Gaussian” distribution and entirely defined by the two parameters: mean and standard deviation. The coefficient of variation symbolized by “V” is the ratio between the standard deviation “” and the mean “X”.
Conditioning
All SN 1, SN 2 and SN 3 standard cements are packaged in screwed and airtight bottles of 40 gr.
Equivalence
We offer the following list of equivalences: NIST, CCRL, NCBM or others.
