USAGE

Sand is used in the test method for determining the characteristic filtration opening of a geotextile

TECHNICAL CHARACTERISTICS

The sand is of the natural siliceous type with a water content of less than 0.1%. The constituent grains of these sands are uncrushed and round-shaped. It has a silica content greater than 98%

The granulometric curve lies within the time zone defined by standard EN ISO 12956

The controls are carried out by the SNL laboratory, and we provide a certificate of analysis upon request during the production of the sand.

The conditioning of sand is done on demand based on your tests.

It is strongly advised to use a ready-to-use customed bags to avoid any segregation and ensure compliance with the zone defined by the standard.

USAGE

It is used on public works sites to measure the bulk density of soils and granular materials. It is used with the “Sand Densitometer” device.

CHARACTERISTICS

This sand is made of dry natural siliceous sand (silica content higher than 97 %), the water content of which is lower than 0,1 %. It is free from flocculent particles, silt, clay and organic matter. The constituent grains of the sand are uncrushed and round-shaped.

The sand is packaged in 25 kg bags.

The grading of replacement sand is according to BS 1377-9 and ASTM®* D 1556.

CONTROLS

These controls are carried out by the SNL laboratory.

USAGE

S.N.L has developed, with the operators of large infrastructure projects, a sand that meets the technical requirements specific to sandboxes (civil engineering). These sandboxes can hold several support points and level a very strong load, for temporary structures and hyper-structures.

References: LOCAPAL, EIFFAGE…

By definition (LERM):

• Realization of calibrations allowing rapid debugging.
• The sand must not have a grain size that would result in a compaction effect.
• Its water content must always be less than 2%.

TECHNICAL CHARACTERISTICS

The sand is of the natural siliceous type with a water content of less than 0.1%. The constituent grains of these sands are uncrushed and round-shaped. It has a silica content greater than 98%

Its granulometric curve is adapted to avoid any compaction effect as soon as the sandbox is correctly sized.

DELIVERY

The sand is packaged in 25 kg bags, and our pallets can contain from 2 to 48 bags.

SNL proposes a full range of stripping sand made of natural silica sand (SiO2>98.5%)

La SNL étudie, à partir de votre besoin de nettoyage des équipements de laboratoire que vous avez, ciment béton…  Et vous propose un sable siliceux lavé, séché.

You can send an inquiry with your detailed needs if you are searching for a specific sand, based on your own specification.

Example :

If you are searching for 1-2 mm cleaning sand: we can propose the following sand:

Descriptif

Deliveries are made individually and on a covered pallet of 2 to 48 bags, protected by a polyethylene cover (road and maritime transport) with reinforced cardboard (maritime transport only). The export pallets are with a NIMP15 treatment.

The cavity inside the fuse body is usually filled with fine silica sand to absorb heat and energy from an overcurrent. For this, it must meet a certain compactness and granular distribution to optimize absorption.

TECHNICAL CHARACTERISTICS

SNL offers a complete range of sand for fusibles based exclusively on pure siliceous sand with + 98% washed, rolled and dried silica

The SNL studies, based on your needs and following the requested standard, any type of sand for fusibles. You can consult us according to your specific needs.

Example of fuse sand that we propose:

USAGE

The phosphorescent sands developed by the SNL are intended for identification under ultraviolet lamp

They are specially designed to be useable in pond water or river water and remain phosphorescent for several years. The sands were tested in an independent laboratory to ensure the innocuity of the sands while used in water, without consequences for aquatic environments.

The most common uses are:

• Monitoring of the consequences of floods and dam releases in rivers: this method was developed by researchers from Electricité de France to identify the presence of sand deposited upstream in samples taken at different distances and times

You will find in our Learning centre the article published by “Electricité de France”  research department

• Hydraulic study in a basin
• Avalanche studies

The use of phosphorescent sand can allow the use of photos, videos and AI to track movements in fluid mechanics, facilitate modelling or confirm mathematical models.

TECHNICAL CHARACTERISTICS

The sand is of the natural siliceous type with a water content of less than 0.1%. The constituent grains of these sands are uncrushed and round-shaped. It has a silica content of more than 98%.

CONTROLES

The sand is controlled under a UV lamp

DELIVERY

The sand is packaged on demand either in small or big bags to facilitate its transport and use in various environments.
