Portland cement compounds SNL 200/201/202/203/204
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

SPECIFIC SURFACE AND SIZE
For the calibration of the Blaine device, follow the prescriptions of standard NF EN 196-6, in particular for any temperature corrections. To determine the volume of the packed layer, it is not essential to use the reference cement, but it must be used systematically:

Determination of macrotexture
CHARACTERISTICS
The sand is natural, siliceous. It is clean, the grains are generally isometric and rounded in shape. It is dried, screened and prepared in a modern workshop offering all guarantees of quality and regularity.
The sand is packaged in polyethylene bags each containing 1000. ± 10 g.
Deliveries are made in boxes of 20 bags weighing 20.5 kg, and in pallets of 36 to 45 boxes with a gross mass of 753 to 935 kg, protected by a polyethylene cover (road transport) or reinforced cardboard (sea transport) .
CONTROLS
The particle size composition, determined by sieving, complies with the requirements of standard NF P98-216-1 (§ 6).
Tamis ouverture des mailles (mm) | Passant cumules (%) |
0.16 | ˂4 |
0.315 | ˃98 |
These analyzes are supplemented by controls of the humidity level.
APPLICATION AREAS
This sand is used to carry out the so-called HSv test: “measurement of the true sand depth”, which consists in characterizing the roughness of a road surface. It provides an average thickness of the hollow asperities of the road layer. It varies from 0.3mm for smooth roads to over 2mm for very rough roads.

SILICE SANDS FOLLOWING STANDARD EN 1097-8 2009
Method for determining the abrasion value of aggregates ( AAV )
This method makes it possible to determine the abrasion value of road aggregates.
The sands produced by the SNL are the sands used to produce the test specimens.
The fine sand less than 0.300 mm is intended for setting the aggregates at the bottom of the mold.
Abrasive sand is fine siliceous sand containing at least 96% silica. All the sand must pass through a 0.85 mm sieve and be retained on the 0.300 mm sieve. In addition, 75% of the fine sand must pass through the 0.600 mm test sieve and be retained on that of 0.425 mmm (it is kept dry in paper bags with a polypropylene fold): it will then be mixed with the resin.
The bags are 25 kg
Glass balls NF EN 13036-1, NF EN 13036-1 standard glass balls

• Set of 10 buckets of 5 kg
• Set of 2 buckets of 15 kg
• Set of 6 buckets of 15 kg
Each order is delivered on a pallet with plastic film protection.
Controls
The particle size determined by sieving complies with the requirements of standard NF-EN 13036-1: at least 90% of the mass of the balls has a diameter between 0.18 mm and 0.25 mm.
Application areas
Measurement of the average depth of the surface macrotexture of a road pavement using a volumetric on-the-job technique.
The method can be used on a wide range of surfaces. However, care should be taken in interpreting the results when the measured depth is outside the interval (0.25 – 5 mm).
