Compressive Strength Explained. Compressive strength is defined as the capacity of a material to resist forces pushing it together, or more technically, the stress that materials can endure under compression. In simple terms, it measures how much load a material can bear before it crushes. Mathematically, compressive strength is calculated as the maximum compressive load a …
