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

To prevent loss of cement paste or water during casting. bs en 12390-2:2019

is the definitive British and European standard for making and curing concrete test specimens. Published by the British Standards Institution (BSI) , it ensures that cubes, cylinders, and prisms are prepared consistently so that strength tests—such as compressive and flexural strength—accurately reflect the concrete's quality. 🏗️ Core Purpose of the Standard The concrete must be filled in layers to

Careful removal is required to avoid edge damage, which can weaken the specimen during a compression test. 4. Final Curing Conditions Published by the British Standards Institution (BSI) ,

The top surface must be finished flat to ensure even loading during testing. 3. Initial Curing and Demolding Timeframe: Specimens typically remain in the mold for Environment: They must be kept at a temperature of 15∘C15 raised to the composed with power C 22∘C22 raised to the composed with power C 20∘C20 raised to the composed with power C

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