Keep the specimens in their molds for a minimum of 16 hours and a maximum of 72 hours. For standard commercial projects, demolding typically occurs after 24 hours. 5. Permanent Laboratory Curing

leaves air voids in the concrete. Every 1% of trapped air can reduce the final compressive strength by roughly 5% to 6%.

The standard ("Testing hardened concrete. Making and curing specimens for strength tests") provides the official European and British framework to eliminate these human variables. This article breaks down the standard's technical requirements into clear, actionable steps for site technicians, lab personnel, and quality managers. 1. Scope and Equipment Requirements

Constructed from non-absorbent, rigid materials (usually cast iron, steel, or heavy-duty plastic) that do not react with cement paste. They must feature a watertight seal at the joints to prevent water loss during compaction.

Dimensions are verified to ensure they meet tolerance standards. Keep the specimens in their molds for a

The standard places higher emphasis on preventing premature moisture loss, which can lead to micro-cracking and lower strength results.

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:

Duration and conditions of initial curing (including temperatures). Permanent Laboratory Curing leaves air voids in the

BS EN 12390-2:2019 the British and European standard that defines the procedures for making and curing concrete specimens for strength tests

In the construction and civil engineering industries, concrete is the most widely used man-made material on the planet. However, the quality of concrete can vary significantly depending on its constituent materials, mixing, placement, and curing conditions. To ensure that a structure is safe, durable, and fit for purpose, engineers rely on standardized tests—most notably compressive strength tests. But a test result is only as reliable as the specimen that was tested. This is where becomes indispensable.
