Includes filling and compacting moulds, surface leveling, marking, curing conditions, and transportation. Curing Requirements: Specimens must remain in moulds for 16 hours to 3 days at

Curing specimens under controlled temperature and humidity conditions.

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?

The moulds must be in perfect condition, clean, and lightly oiled to prevent the concrete from sticking. The concrete sample is then re-mixed thoroughly on an impermeable surface to ensure uniformity before being placed into the mould. The standard specifies that the mould should be overfilled slightly to account for compaction. The amount of concrete used should be such that after compaction, a layer of concrete remains above the rim of the mould, ideally 10% to 20% of the specimen's height. This ensures a flat, flush final surface. bs en 12390-2:2019

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:

The standard is an essential tool for anyone involved in the construction industry, from engineers and architects to contractors and materials scientists.

BS EN 12390-2:2019 is the most recent version of a standard whose origins trace back to the early days of modern concrete testing. The standard forms part of the BS EN 12390 multi-part series, which collectively addresses the comprehensive testing of hardened concrete. The 2019 edition represents a significant update that supersedes the previous BS EN 12390-2:2009 edition, which is now formally withdrawn. What is BS EN 12390-2:2019

Place the specimens in a room with a relative humidity of ≥ 95% and a temperature controlled at 20 °C ± 2 °C .

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.

specifies the method for preparing and curing test specimens (cubes, cylinders, or beams) for strength tests. It is part of the BS EN 12390 series, which covers various aspects of testing hardened concrete. The standard specifies that the mould should be

The document outlines specific laboratory and field procedures to maintain the integrity of concrete samples from the moment they are cast until they are tested for hardened strength:
