BS EN 12390-2:2019 defines the standardized methods for making and curing concrete test specimens, such as cubes, cylinders, and prisms, to ensure accurate compressive and flexural strength results. The standard outlines specific procedures for molding, compaction, and environmental curing controls required for quality assurance and regulatory compliance. For more details, visit BSI Knowledge.

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:

Conclusion
for hardened concrete testing. Its implementation is vital for: Quality Control Objective: To estimate the strength of concrete in
- Water Curing: Specimens are fully submerged in water maintained at 20°C ± 1°C.
- Humidity Curing: Specimens are stored in a cabinet or room at 20°C ± 1°C and not less than 95% relative humidity. The standard now gives clearer guidance on when each method is appropriate, particularly for testing that simulates in-situ conditions versus standard strength development.
