, followed by underwater curing or humidity-controlled storage until testing. BSI Knowledge

After casting, specimens must be protected from evaporation, shock, and extreme temperatures. For the first 24 hours (the initial curing period), the standard recommends storing the moulded specimens at a temperature of 20°C ± 5°C and near 100% relative humidity, often achieved by covering with plastic sheeting or damp mats. bs en 12390-2:2019

BS EN 12390-2:2019 is the British Standard that specifies methods for for concrete strength tests . It provides a standardized framework to ensure that concrete cubes, cylinders, and prisms are prepared consistently, which is critical for accurate compressive strength assessments. 🏗️ Key Procedural Steps BS EN 12390-2:2019 is the British Standard that

Under ISO/IEC 17025 (laboratory accreditation), simply following the standard is not enough – you must prove you followed it. The standard also specifies the tools for compaction

The standard also specifies the tools for compaction. Depending on the consistency of the concrete, this may include internal vibrators (poker vibrators), vibrating tables, or manual tamping rods. For manual compaction, the rod must be circular in cross-section, straight, and made of steel with a smooth finish. The Making of Test Specimens
