BS EN 12390-2:2019 is the British and European standard that dictates the procedures for making and curing concrete specimens for strength testing. It is a critical document for ensuring that concrete samples (typically cubes or cylinders) are prepared consistently so that strength results are accurate and comparable. What This Standard Covers

The standard outlines specific requirements for curing specimens, including: bs en 12390-2:2019

B. Site Curing (Matched Curing)

  • Objective: To estimate the strength of concrete in the actual structure.
  • Method: Specimens are stored under conditions that mimic the structural element. For example:

    : Standardizing the laboratory and site conditions for specimen preparation to minimize variability in test results. Relationship to Other Standards : It is often used in conjunction with BS EN 12350-1 (sampling fresh concrete) and BS EN 12390-3 (compressive strength testing). 2. Key Procedures for Making Specimens BS EN 12390-2:2019 is the British and European

    Critical requirement: Do not over-vibrate. Over-vibration causes aggregate settlement to the bottom and a weak laitance layer on top. Do not under-vibrate—this leaves voids. Objective: To estimate the strength of concrete in
