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.
- laser fineness and granulometry,
- chemical composition.
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
In box of 5 bottles of 5 gr screwed and waterproof

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:
- after 1000 tests;
- when using another type of manometric liquid, another type of filter paper, a new pressure gauge tube or a new perforated disc;
- in the event of systematic deviations from the secondary reference cement.

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 )
PROPERTIES OF SANDS EN 1097-8
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.
Formulation
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.
Conditioning
The bags are 25 kg

Silica fines EN 13075 1-2
Silica fines EN 13075 1-2 emultion breakage index
SNL silica fines for emultion breakage index EN 13075 1-2
FEATURES
SNL silica fines for breaking index for emulsions EN 13075 1-2 is a fine sand of the same origin as the old sikaisol;
Following the out of stock of SIKAISOL sand, SNL has developed and perfected a sand that meets the requirements of the standard “Determination of the fracture index of cationic bitumen emulsions, Mineral fines method” EN 13075 1-2
The advantage of this new sand is its reproducibility
- The level of silica is stable at + 98% (which is a guarantee of stability of the chemistrycompared to the product composed of different materials)
- The production is carried out mechanically and industrially (screened and mixed): this ensures the stability of the product (physical)
- In addition, SNL will guarantee the sustainability of its product (as for all our product families)
The marketing is carried out in buckets of 5 kg or 25 kg
CONTROL:
For each production batch, we guarantee you a certificate of conformity guaranteeing compliance with the table:
Fines for emultion breakage index EN 13075 1-2#SNL silica fines for breaking index of emulsions EN 13075 1-2#Fines for emultion breakage index EN 13075 1-2#Silica fines EN 13075 1-2 emultion breakage index
