: Concrete is filled in layers and compacted using methods like: Mechanical : Internal poker vibrators or vibrating tables.

To adhere to the standard, specific equipment must be used. Molds must be made of a non-absorbent, rigid material that does not react with cement paste. They must be watertight and capable of maintaining their shape under the pressure of compaction. Common materials include steel, cast iron, and certain high-density plastics. bs en 12390-2:2019

is the British Standard that dictates the procedures for making and curing specimens for strength tests on hardened concrete . It is a critical document for ensuring the consistency and reliability of compressive strength results in construction projects. Key Procedures in BS EN 12390-2:2019 : Concrete is filled in layers and compacted

Using a vibrating table or internal "poker" vibrator. Hand Compaction: Using a standard tamping rod or bar. They must be watertight and capable of maintaining
