The theoretical compressive strength of concrete is eight times larger than its tensile strength. This implies a fixed relation between the compressive and tensile strength of concrete. In fact there is a close relation but not a direct proportionality. The ratio of tensile to compressive strength is lower for higher compressive strengths.
[PDF]Crushing Strength. Sometimes known as compression strength parallel to the grain, this is a measurement of the wood's maximum crushing strength when weight is applied to the ends of the wood (compression is parallel to the grain). This number is a good indicator of the wood's strength in applications such as deck posts, chair legs,...

[PDF]Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).
