Bs En 12390-2:2019 〈Proven〉

Specifies curing procedures for laboratory and field conditions. 1. Preparing and Casting Specimens

Every batch of test specimens must be accompanied by a report. According to the standard, this documentation must include: Unique identification of the specimen. Date and time of preparation. Details of the compaction method used.

Improper curing is the leading cause of unrepresentative low-strength test results. BS EN 12390-2:2019 splits curing into two distinct stages: initial on-site curing and long-term laboratory curing. Initial Curing (In the Mold)

Specimens are typically demoulded after a minimum of 16 hours and a maximum of 28 hours. Take extreme care during this process; hitting the mould excessively can micro-fracture the young concrete, permanently compromising its ultimate strength. Final Curing (Until Testing) According to the standard, this documentation must include:

In concrete construction, compressive strength is the ultimate measure of quality and safety. To ensure that laboratory test results accurately reflect the potential strength of the concrete delivered to a site, the sampling and preparation process must be flawlessly standardized. is the British and European standard that dictates exactly how to make and cure concrete test specimens for strength testing.

The Concrete Society provides invaluable guidance on how BS EN 12390-2:2019 is applied in practical on‑site conditions. Cubes should be made and as near to their final storage position as is practicable. The key steps for on‑site cube making include: A soft-faced mallet (rubber or plastic) used to
