To prevent loss of cement paste or water during casting. Using a vibrating table or internal "poker" vibrator
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 🛠️ Key Procedures and Requirements 1
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:
The concrete must be filled in layers to ensure full density without segregation. Acceptable compaction methods include:
Defining exactly how to fill and compact molds.
