The 2019 version introduced clarifications and updates from its predecessor (2009). Key technical requirements include:
This article provides a comprehensive overview of BS EN 12390-2:2019 based on publicly available information. For definitive technical requirements, readers should purchase and reference the official standard document from BSI or an authorised distributor.
For on-site cube making, the standard recommends filling moulds in and compacting each layer with a steel tamping bar. The number of tamps per layer is specified as: bs en 12390-2:2019
Once cured, the specimens must be transported to the testing machine (such as a compression testing rig) with care to avoid any impact or damage that could compromise the test results.
Duration and conditions of initial curing (including temperature records). Duration and conditions of final curing. Any deviations from the standard method. Conclusion The 2019 version introduced clarifications and updates from
Curing is arguably the most critical aspect of the standard, as it directly impacts the hydration process and strength development. distinguishes between laboratory curing and site curing. 2.1 Initial Curing
The concrete must be placed in the molds and compacted in layers. The number of layers and the method of compaction depend on the consistency of the concrete and the compaction equipment used. For on-site cube making, the standard recommends filling
BS EN 12390-2:2019 recognises the equivalence of different curing environments. Curing specimens in a closely regulated humidity chamber is considered equivalent to curing in water, provided the correct conditions are maintained.
The term "curing" refers to providing adequate moisture, temperature, and time to allow concrete to achieve the desired properties for its intended use. .
