Why is Salt Crystallisation Testing Important?

Salt crystallisation is a common cause of deterioration in natural stone materials. When salts penetrate the stone and crystallise, they can cause significant damage, leading to structural weaknesses and aesthetic degradation. This is particularly problematic in environments exposed to saltwater or de-icing salts. The BS EN 12370:2020 standard provides a reliable method to assess the stone's resistance to such damage, ensuring that only the most durable materials are used in construction projects.

Comprehensive Testing Methodology

The BS EN 12370:2020 standard outlines a rigorous testing procedure that simulates the conditions under which salt crystallisation occurs. This involves subjecting stone samples to cycles of immersion in a salt solution followed by drying. The standard specifies the concentration of the salt solution, the duration of immersion and drying cycles, and the number of cycles to be performed. By following these guidelines, testers can accurately assess the stone's resistance to salt crystallisation.

Benefits of Using BS EN 12370:2020

• Ensures Quality: By adhering to this standard, manufacturers and builders can ensure that the natural stone used in their projects meets high-quality standards for durability and resistance.
• Reduces Maintenance Costs: Using stone that is resistant to salt crystallisation can significantly reduce maintenance and repair costs over the lifespan of a building or structure.
• Enhances Safety: Structures built with stone that meets the BS EN 12370:2020 standard are less likely to suffer from structural failures due to salt damage, enhancing overall safety.
• Preserves Aesthetic Appeal: Natural stone that resists salt crystallisation maintains its appearance over time, preserving the aesthetic appeal of buildings and monuments.

Who Should Use This Standard?

The BS EN 12370:2020 standard is a valuable resource for a wide range of professionals, including:

• Architects and Designers: To select materials that will maintain their integrity and appearance over time.
• Construction Engineers: To ensure that the materials used in construction projects are durable and reliable.
• Stone Suppliers and Manufacturers: To provide clients with high-quality stone products that meet industry standards.
• Quality Control Specialists: To verify that stone materials meet the necessary resistance criteria before use.

Conclusion

The BS EN 12370:2020 standard is an indispensable tool for anyone involved in the selection, testing, or use of natural stone materials. By providing a clear and reliable method for assessing resistance to salt crystallisation, this standard helps ensure that natural stone products are both durable and aesthetically pleasing. Whether you are an architect, engineer, or stone supplier, adhering to this standard will help you deliver superior quality and performance in your projects.
