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, Cl.16.59(6): The size of the test cube shall be 100 mm for concrete with the maximum aggregate size not exceeding 20 mm and

What is Compressive Strength? - Matmatch

Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size of that material, or structural element, when applied. A force is applied to the top and bottom of a test sample, until the sample fractures or is deformed.. Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases
