The standard BS EN 12390-2:2019 focuses on the preparation and curing of hardened concrete specimens for strength testing.

BS EN 12390-2:2019 supersedes the 2009 edition and specifies procedures for making and curing test specimens from fresh concrete. Its primary purpose is to minimize variability introduced during specimen preparation, ensuring that the measured strength reflects the actual quality of the concrete in the structure, rather than artifacts of sample handling. The standard applies to specimens intended for compressive, flexural, or splitting tensile strength tests, covering both laboratory-cured specimens (for quality control and acceptance testing) and field-cured specimens (for assessing when formwork can be removed or when a structure can be loaded).

Notably, the standard includes a flexibility provision: it can also be used for the making and curing of specimens intended for other test methods beyond strength testing. bs en 12390-2:2019

Testing Hardened Concrete – Part 2: Making and Curing Specimens for Strength Tests

: Specifies the requirements for molds, compacting equipment (such as vibrating tables), and finishing tools like floats. The standard BS EN 12390-2:2019 focuses on the

The process of making concrete specimens must be executed systematically to prevent segregation of aggregates and ensure uniform density. Step 1: Preparation of Moulds

In the world of construction, concrete is the backbone of our infrastructure. However, the material's strength and long-term durability are not determined by guesswork. They are proven through rigorous, standardized testing. At the heart of this process lies the standard , a critical document that ensures every concrete sample is prepared and cured in a consistent, reliable manner. Officially titled "Testing hardened concrete – Making and curing specimens for strength tests," this standard is the definitive guide for technicians, quality control staff, and civil engineers across the UK and Europe. The standard applies to specimens intended for compressive,

Curing is arguably the most sensitive phase of specimen preparation. Cement requires a continuous supply of moisture to undergo hydration and gain strength. Initial Curing (First 16 to 28 Hours)

Maintaining specific environmental conditions (temperature, humidity) to ensure proper hydration and strength development before testing.

Proper mould preparation is fundamental to producing reliable test specimens. According to the standard, moulds must be clean and lightly oiled to prevent concrete adhesion and facilitate demoulding.
