The standard has ISBN 9780580984372 and falls under ICS code 91.100.30 (Concrete and concrete products). It is available in PDF format (published 19 July 2019) and can be purchased directly from BSI or through various standards distributors.
. By standardizing how test cubes, cylinders, and prisms are handled, it ensures that the physical properties of the hardened concrete are measured accurately and consistently across different construction projects. Scope and Purpose
Leave the specimens in the molds for at least 16 hours, but no longer than 3 days. The typical practice is 24 hours.
Standard tests are usually conducted at 7 or 28 days to determine compressive strength, but some studies extend curing to 90 days. Importance of Compliance bs en 12390-2:2019
Using a vibrating table or internal "poker" vibrator. Hand Compaction: Using a standard tamping rod or bar.
: Outlines how to fill molds and compact concrete to remove entrapped air, which is vital for achieving a representative strength profile.
Compacting and forming concrete cubes, cylinders, or prisms. The standard has ISBN 9780580984372 and falls under
I can provide specific checklists or tailored advice based on your testing environment. Share public link
A temperature-controlled water tank or a mist room capable of maintaining the required environment. 3. Step-by-Step Procedure for Making Specimens
The 2019 edition adds clarity on transporting specimens from the site to the laboratory, stipulating that they must be protected from vibration, impact, and temperature extremes. Mishandling can induce micro-cracks that significantly reduce apparent strength. By standardizing how test cubes, cylinders, and prisms
Plastic sheeting or damp burlap/hessian is typically used to cover specimens immediately after casting to prevent moisture loss during initial curing. Standard Overview
This article provides an informative overview of the standard, its scope, and the key technical requirements for industry professionals.
Understanding BS EN 12390-2:2019: The Standard for Making and Curing Concrete Test Specimens
The main goal of BS EN 12390-2:2019 is to eliminate variables in the preparation process. If specimens are made or cured incorrectly, the resulting strength data may be falsely low, leading to unnecessary project delays or costly structural disputes. Key functions include:
