Moulds must be made of a non-absorbent, rigid material that does not react with cement paste (typically cast iron, steel, or heavy-duty plastics). Standard sizes are 100 mm or 150 mm.
Specimens must be identified and tagged immediately to track their batch and date of casting. 2. Initial Curing
Proper mould preparation is fundamental to producing reliable test specimens. According to the standard, moulds must be clean and lightly oiled to prevent concrete adhesion and facilitate demoulding.
The primary purpose of BS EN 12390-2:2019 is to specify the methods for:
The standard outlines specific requirements for curing specimens, including:
Specimens are typically demoulded after a minimum of 16 hours and a maximum of 28 hours. Take extreme care during this process; hitting the mould excessively can micro-fracture the young concrete, permanently compromising its ultimate strength. Final Curing (Until Testing)
Great care must be taken when removing the moulds. If the concrete is damaged during this process, the specimen is compromised. Once demoulded, the specimens should be marked clearly and permanently.
The standard applies to specimens formed in moulds, including:
