between cube and cylinder curing methods.

By standardizing these variables, the industry ensures that a concrete cube tested in London behaves exactly like a cube tested in Paris or Frankfurt, removing human error and environmental bias from the strength verification process. Required Equipment and Lab Setup

In concrete construction, compressive strength is the primary metric used to verify that a structure will safely bear its intended design loads. However, a compressive strength test is only as reliable as the specimen being tested. If a concrete cube or cylinder is cast poorly, compacted insufficiently, or cured under incorrect temperature and humidity conditions, the test results will be artificially low. This leads to costly, unnecessary structural investigations or project delays. bs en 12390-2:2019

Placement in a mist room or environmental chamber maintained at 20°C (± 2°C) with a relative humidity ( RH ) of ≥ 95% .

: Standardizing preparation ensures that variations in test results are due to the concrete mix itself, not how the specimen was handled. between cube and cylinder curing methods

A temperature-controlled water tank or a mist room capable of maintaining required environmental levels. Step-by-Step Procedure for Making Specimens

Compaction must continue until no further large air bubbles emerge on the surface, and the surface becomes relatively smooth with a glint of cement paste. BS EN 12390-2 permits three primary compaction methods: However, a compressive strength test is only as

Great care must be taken when removing the moulds. If the concrete is damaged during this process, the specimen is compromised. Once demoulded, the specimens should be marked clearly and permanently.

This is the most significant update in the 2019 edition. The standard distinguishes between two curing regimes:

Use a standard compacting bar. Distribute strokes uniformly across the cross-section. Ensure the rod penetrates into the underlying layer without striking the bottom of the mold. 4. Surface Finishing

The construction industry relies heavily on the use of concrete as a building material, and ensuring its quality and durability is crucial for the safety and longevity of structures. One of the key standards that governs the testing of hardened concrete is BS EN 12390-2:2019. This European Standard provides a comprehensive framework for the testing of hardened concrete, covering various aspects such as compressive strength, flexural strength, and other mechanical properties.
