Accurately predicting the concrete strength prevents structural failure.
For professionals looking to stay compliant, the full standard can be accessed via BSI Knowledge or official Standard Distributors . BS EN 12390-2:2019 - TC | 31 Jul 2019 | BSI Knowledge
Stricter requirements for recording and logging daily curing tank temperatures to ensure traceability and quality assurance. Conclusion
Technical Overview: BS EN 12390-2:2019 BS EN 12390-2:2019 is a European standard adopted by the British Standards Institution (BSI) that specifies the methods for making and curing specimens for strength tests
Duration and conditions of initial curing (including temperature records). Duration and conditions of final curing. Any deviations from the standard method. Conclusion
Moulds must be non-absorbent, rigid, and clean. Before casting, they must be thinly coated with a mould release agent (like mineral oil) to prevent the concrete from sticking, while ensuring the coating does not affect the concrete properties. 1.2 Filling and Compaction
Curing is perhaps the most vital step in the preparation of concrete specimens. BS EN 12390-2:2019 outlines strict parameters for both initial and long-term curing. Initial Curing
: It ensures that a 28-day strength test in one lab is directly comparable to a test in another.
In the construction industry, the compressive strength of concrete is the primary metric for structural quality. However, the accuracy of this metric relies heavily on consistency. How a concrete sample is treated between the time it is cast and the time it is tested can drastically alter the results.
