What is BS EN 12620:2010?

BS EN 12620:2010 is a technical standard that sets out the specifications for aggregates used in concrete. It provides guidelines for the size, shape, grading, and quality of aggregates, which are crucial components in the production of strong and durable concrete.

The Importance of BS EN 12620:2010

Adhering to BS EN 12620:2010 ensures that the aggregates used in concrete meet specific standards. This is essential as it directly impacts the performance and integrity of the final concrete product. The standard establishes requirements for both natural and recycled aggregates, promoting sustainable practices in construction. By complying with BS EN 12620:2010, construction professionals can enhance the strength, durability, and overall quality of their concrete structures.

Key Specifications in BS EN 12620:2010

BS EN 12620:2010 covers various aspects of aggregates, including but not limited to:

Particle size distribution: Aggregates must possess a well-graded particle size distribution, ensuring optimal packing and reducing the voids in the concrete mix.

Shape and texture: The standard defines requirements for both angular and rounded particles, considering factors such as strength, workability, and water demand.

Cleanliness: Aggregates should be free from excessive dust, clay, or other impurities that may affect the properties of the concrete.

Strength and abrasion resistance: BS EN 12620:2010 sets minimum requirements for the compressive strength and resistance to wear and tear of aggregates.

Ensuring Compliance with BS EN 12620:2010

To ensure compliance with BS EN 12620:2010, construction professionals and aggregate suppliers must conduct regular testing. This involves evaluating the properties of aggregates, such as particle size distribution, water absorption, and mechanical strength. By conducting these tests, it becomes possible to verify if aggregates meet the specified standards outlined in the standard.

Furthermore, construction projects should include clear specifications for the use of aggregates. This ensures that all parties involved, from architects to contractors, are aware of the requirements set by BS EN 12620:2010.

In conclusion, BS EN 12620:2010 is a crucial technical standard that sets out the specifications for aggregates used in concrete. It plays a significant role in ensuring the quality and performance of concrete structures. Adhering to this standard allows construction professionals to create stronger, more durable, and sustainable buildings.
