CONCRETE - Boral

Strength of concrete The compressive strength of concrete is measured by how much force is required to crush it, this is important in the design of structures. In pavements and other slabs on the ground, the design is usually based on flexural strength, (i.e.; how much force the concrete can withstand in bending before it breaks).
