This article provides an in-depth look at the requirements of this crucial standard and how it is applied in the field. What is BS EN 12390-2:2019?
Before casting begins, all equipment must be verified against the physical constraints outlined in the standard. Mould Dimensions and Suitability
: Requiring detailed reporting of sampling, compaction, and curing conditions to maintain accountability.
This modular approach allows laboratories to adopt the specific standards they need. For example, a lab might use Part 2 for specimen preparation, Part 3 for compressive strength testing, and Part 7 for density checks, all working in harmony to provide a complete picture of the concrete's performance. bs en 12390-2:2019
Compared to the 2009 version, BS EN 12390-2:2019 includes several technical refinements:
By enforcing strict quality control during the casting and curing phases as mandated by BS EN 12390-2:2019, stakeholders ensure that the lab results genuinely reflect the potential strength of the concrete delivered to the structure.
alters the rate of cement hydration. High initial temperatures can boost early strength but severely punish the 28-day ultimate strength. This article provides an in-depth look at the
The standard provides a rigorous framework for preparing specimens used primarily for compressive and flexural strength testing. It covers the entire lifecycle of a test specimen, including: Preparation : Using non-reactive release agents to prevent sticking. : Layering concrete based on consistency. Compaction
: When moving specimens to a laboratory, they must be protected from dehydration and temperature extremes using wet sand, sawdust, or sealed plastic bags. Significance in Construction The 2019 version supersedes the earlier 2009 edition and aligns with the broader EN 12390 series
This part of the EN 12390 series applies to specimens made from concrete with a maximum aggregate size of 40 mm or less. It covers the preparation of cubes, cylinders, and prisms. The standard is used both for specimens made in a laboratory setting and those made on-site to verify the quality of concrete being delivered to a structure. Essential Equipment Requirements Compared to the 2009 version, BS EN 12390-2:2019
Method of permanent curing (water vs. high humidity) and duration.
BS EN 12390-2:2019 is a critical standard that governs the testing of hardened concrete. The standard provides a comprehensive framework for testing compressive strength, flexural strength, and other mechanical properties. By following the guidelines outlined in the standard, testing laboratories, concrete producers, and construction companies can ensure that their concrete meets the required strength and durability specifications. This, in turn, ensures that structures are safe, long-lasting, and compliant with European and UK regulations.
Stricter guidance on the temperature tolerances during the transport of specimens from the construction site to the testing laboratory.
