By adhering to the entire family of standards, laboratories create a closed-loop system of precise measurement, ensuring that every step of testing is trustworthy.
By following BS EN 12390-2:2019 meticulously, you ensure that the compressive strength result reflects the concrete – not the mistakes of the technician. That is the essence of standardized testing.
) and protected from moisture loss by covering them with plastic or wet burlap.
between cube and cylinder curing methods. bs en 12390-2:2019
Before placing concrete, clean the internal surfaces of the molds thoroughly. Apply a thin coat of non-reactive release oil to prevent the concrete from sticking. Ensure all joints are tightly sealed to prevent water leakage. 2. Sampling and Filling
The standard provides a detailed, step-by-step guide to the entire specimen preparation process, including:
Procedures for making and curing specimens (cubes, cylinders, and prisms) for strength tests. Key Steps: By adhering to the entire family of standards,
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.
As a harmonized European standard, BS EN 12390-2:2019 superseded the previous 2009 version and has been essential for compliance with UK construction regulations even after Brexit. This article provides a detailed look at the standard, breaking down its key requirements, procedures, and why it is indispensable for any construction quality assurance process.
Compaction must continue until the concrete is fully consolidated without causing segregation. The standard permits three main methods: ) and protected from moisture loss by covering
Insert the poker vertically across a grid of points, ensuring it does not touch the bottom or sides of the mold. Withdraw the poker slowly to allow the hole left by the vibrator to close cleanly.
The curing continues until the scheduled testing date (e.g., 28 days). 4. Test Day Procedures
Crucially, the standard distinguishes between two types of curing environments that can be used depending on the objective of the test:
Store the molds in an environment maintained at
By stringently adhering to BS EN 12390-2:2019, laboratory testers and civil engineers can guarantee that structural concrete calculations are backed by accurate, repeatable, and completely compliant data.
