Concrete Cube Testing: The Process. To test the strength of fresh concrete, cube samples are made in 100mm or 150mm cube moulds. A sample of the mix is taken per BS EN 12350-1 (verification required for BS EN number) and a set of six cubes are made per BS EN 1881-108 or its replacement BS EN 12390-2. The cubes are soaked in a controlled …
