Sandblasting, an essential technique in industry, relies on an often underestimated ingredient: sand. This abrasive material is at the heart of many industrial processes, guaranteeing both efficiency and precision. But what makes sandblasting sand a strategic choice?

The qualities of sandblasting sand:
To obtain optimal results, the sand used must meet specific criteria:

High purity: A silica content of more than 95% ensures consistent performance and limits equipment wear.
Homogeneous particle size: It guarantees uniform abrasion and precise surface treatment.
Suitable hardness: High hardness is essential for stripping resistant materials such as metal or stone.
Low impurity rate: Impurities can affect the quality of the work or damage equipment.

Various applications:
Sandblasting sand is widely used in different sectors:

Construction and renovation: Cleaning facades, stripping old paint or removing graffiti.
Mechanical industry: Deoxidation and preparation of metal surfaces.
Crafts: Engraving patterns on glass or stone.

Why choose quality sand?

Good sandblasting sand is not only effective. It reduces long-term costs by preserving equipment and ensuring precise results. In addition, it contributes to compliance with environmental standards by limiting dust emissions.

Sandblasting sand is an essential material for many industries. Its choice, guided by rigorous technical criteria, directly determines the quality of the work carried out.

In the construction and roofing industries, bitumen felt is a trusted solution for waterproofing and protection. One essential component in its production is sand. While it might seem like a minor ingredient, sand plays a crucial role in enhancing the performance and durability of bitumen felt. Let’s uncover why.

Key Characteristics of Sand for Bitumen Felt:

To ensure optimal performance, the sand used in bitumen felt must meet specific criteria:

Adhesion: Sand with the right texture promotes a strong bond with bitumen, ensuring a durable final product.

Granulometry: Uniform grain size provides consistent coverage and prevents irregularities during application.

Heat Resistance: High-quality sand withstands the thermal demands of bitumen production without degradation.

Eco-Friendly Sourcing: Sustainable practices ensure the sand’s quality while minimizing environmental impact.

Applications of Sand in Bitumen Felt Manufacturing:

Sand is integral to multiple aspects of bitumen felt production:

Surface Layer: Sand creates a non-slip surface, enhancing safety during installation.

Protection: It shields the bitumen from UV rays and physical wear, extending the product’s lifespan.

Structural Integrity: Sand contributes to the overall strength and resilience of the bitumen felt.

Why Quality Sand Matters:

The quality of sand directly impacts the durability and functionality of bitumen felt. Inferior sand can lead to weak adhesion, reduced weather resistance, and premature failure of the material. High-grade sand ensures reliable performance, even under harsh conditions.

Sand is an indispensable ingredient in bitumen felt, providing strength, protection, and longevity. Its careful selection is a critical factor in delivering high-quality waterproofing solutions.

According to archaeological studies, mining activity in Algeria has been known since antiquity. In addition, many vestiges of a mining activity during the Roman era have been identified such as the exploitation of copper in Ouenza, silver-bearing lead in Sidi Kamber, marble in Filfila, salt in the Chotts.

Between the two world wars, Algeria was one of the major producers of iron ore in the world. In 1930, iron ore extracted from Algerian deposits was exported to many countries. It was mainly exported to England (1 million tons), to the Netherlands (700,000 tons), to the United States (300,000 tons), to Germany, to Italy, to Belgium.

Algeria is a vast and underexplored country. It has a rich and varied geological and mineral potential, which is attractive for investment and partnership aimed at mining exploration, development and production of certain mineral substances.

Diatomite: siliceous sedimentary rock, loose or consolidated, of light color, formed mainly of remains of diatoms.

Other names: terre à diatomées; tripoli; kieselguhr

Use: Due to its lightness, its porosity and its chemical neutrality, it is used in particular for the filtration of liquids and as a natural mineral filler.

Global diatomite deposits are classified into two categories: marine or continental deposits.

In France, all diatomite deposits are continental in type and are located in the Massif Central. Two of these deposits are currently exploited: Saint-Bauzile, in Ardèche and Virargues-Foufouilloux in Cantal.
Geological resources in diatomites are relatively abundant on French soil and recognized to be of good quality.
o Nevertheless, exploitable reserves are more limited, in particular due to environmental constraints (the Nouvialle deposit (Cantal) appears to be one of the most important continental diatomite deposits in Europe but not exploited).
o Regarding the deposits currently in operation, the known reserves are estimated at around 20 years of operation (it will probably be difficult to maintain French production and supply the two diatomite processing plants) .

Industrial players, markets and sectors

2 main French operators (diatomite deposits): the Chemviron and Imerys groups.
There are 4 active careers:
• the Montagne d’Andance quarry (Chemviron)
• the Foufouilloux-Pré de l’Ane quarry (Chemviron)
• the Foufouilloux-Nord quarry (Imerys)
• the Foufouilloux-Pré quarry in Nozerolles (Imerys)

The maximum authorized production for these 4 quarries is 460,000 t.
Actual production: around 300,000 t of raw materials extracted, corresponding to a national production of diatomite market products of 100,000 t.

Total world production: is around 3 Mt, dominated by the United States (700,000 t in 2017).

On the demand side, the distribution of markets varies by geographic area.
o At the global level (in particular in the United States), the first market are the filtration aids with 50% of the demand.
o then the production of cement (30%), where diatomite is used as an additive,
o mineral fillers and fillers (15%) used in many applications such as paint, plastics or papers.
o Absorbents correspond to 5% of the uses of diatomite, in particular for the elimination of microbes and contaminants in public water systems.
o less than 1% of applications are specialty uses including pharmaceutical and biomedical uses (filtration of blood plasma, DNA extraction, etc.)
