CEMENT - MARBLE

Compliance of Cement and Marble Products with Libyan Standards

Technical and Mechanical Standards for Cement and Marble Products

The technical requirements set by the Libyan National Standards and Metrology Center aim to enhance the quality of cement and marble products and define the standards for international trade. HRN Inspection is responsible for ensuring that products exported from Turkey to Libya meet these standards. Below is an analysis of the products:

Cement Tile Products

Normal Cement Tiles

• Made of sand and cement.
• Produced in single-layer or double-layer formats.
• Can be a homogeneous mixture or reinforced with different materials on the surface.

Reinforced Cement Tiles

• The surface layer contains chemical, polymeric, metallic substances, or glass fiber.
• More durable with a lower water absorption rate.

Coated Cement Tiles

• The surface layer contains hard stones such as marble or granite.
• Enhanced aesthetic and durability properties.

Technical Requirements:

• Thickness: Minimum 15 mm for normal tiles; thicker for reinforced tiles.
• Water Absorption Rate: Maximum 12%.
• Abrasion Resistance: Up to 0.8 mm wear limit.

Sampling and Testing Methods:

• Tested using ISO standard methods (e.g., tensile strength, water absorption rate).
• The physical and chemical durability of the products ensures safety during international shipping.

Natural Marble Tiles

Calcareous Marble Tiles

• Contains a high percentage of calcium carbonate (95%).
• Popular for aesthetics and durability.

Dolomitic Marble Tiles

• Contains calcium and magnesium carbonate.
• Moderately hard and durable.

Travertine Marble Tiles

• Known for its porous structure.
• Commonly used for decorative purposes.

Serpentine Marble Tiles

• Contains serpentine mineral.
• Highly durable and has a unique aesthetic.

Technical Requirements:

• Thickness: At least 10 mm.
• Water Absorption Rate: Up to 5% for travertine tiles; maximum 0.2% for other types.
• Abrasion Resistance: At least 10.

Physical and Mechanical Tests:

• Specific gravity, density, water absorption, and bending resistance tests are performed according to ASTM C 1353 standard.

HRN Inspection's Role

HRN Inspection inspects cement and marble products exported from Turkey to Libya for compliance with the requirements set by the Libyan National Standards and Metrology Center. These inspections ensure that the products meet quality standards and enhance their competitiveness in the international market.

Why HRN Inspection?

• Checks the physical, chemical, and mechanical compliance of products.
• Issues conformity certificates for compliance with Libyan standards.
• Contributes to ensuring secure and sustainable trade.

Conclusion

Cement and marble tiles must meet high standards of durability, aesthetics, and functionality. The criteria set by the Libyan National Standards and Metrology Center increase quality in the construction sector, while the services provided by HRN Inspection guarantee that products meet these standards. HRN Inspection plays a crucial role in the export process to Libya, as proper inspection ensures that the products are durable and reliable.
