The concrete must be filled in layers to ensure full density without segregation. Acceptable compaction methods include:

Treated with a non-reactive release agent for easy demolding. 2. Filling and Compaction

Specifying temperature and moisture conditions for hydration. bs en 12390-2:2019

Once demolded, specimens must be cured until the time of testing. Standard methods include:

Careful removal is required to avoid edge damage, which can weaken the specimen during a compression test. 4. Final Curing Conditions The concrete must be filled in layers to

) and protected from moisture loss by covering them with plastic or wet burlap.

The main goal of BS EN 12390-2:2019 is to eliminate variables in the preparation process. If specimens are made or cured incorrectly, the resulting strength data may be falsely low, leading to unnecessary project delays or costly structural disputes. Key functions include: bs en 12390-2:2019

To prevent loss of cement paste or water during casting.
