The standard mandates that moulds must be rigid, non-absorbent, and capable of retaining their shape. It provides precise dimensional tolerances (e.g., for 150 mm cubes, the tolerance is typically ±0.2 mm) and specifies that the internal surfaces must be smooth and free from defects. A significant emphasis is placed on the verification of mould dimensions, recognizing that worn or warped moulds produce non-standard specimens that yield inaccurate strengths. bs en 12390-2:2019

Q: What are the benefits of using BS EN 12390-2:2019? A: The benefits of using BS EN 12390-2:2019 include improved accuracy, increased confidence in the quality and durability of concrete, and compliance with European and UK regulations.

Note: Any deviation from these temperature ranges can drastically alter the rate of strength gain, rendering the final compression test inaccurate. 5. Key Updates in the 2019 Version Details of the compaction method used (manual vs

The permissible methods of compaction to accommodate modern concrete mixes (like self-compacting concrete).

The standard BS EN 12390-2:2019 focuses on the preparation and curing of hardened concrete specimens for strength testing. It provides precise dimensional tolerances (e

A non-reactive oil or chemical compound applied thinly to the inside of the mold to prevent the concrete from sticking without affecting the hydration process.

The scope of BS EN 12390-2:2019 includes:

Compaction is vital to remove entrapped air and achieve maximum density. The standard accepts different methods, with hand tamping being most common on-site:
