In HK, 100 mm cubes are commonly used for determining the compressive strength of concrete as the maximum aggregate size used in concrete mixes is normally 20 mm. According to GS 2006, (6): The size of the test cube shall be 100 mm for concrete with the maximum aggregate size not exceeding 20 mm .
Before the concrete is scooped into the moulds, the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.
