### Compressive Strength of Concrete - CivilWeb Spreadsheets

Compressive Strength of Concrete. The compressive strength of concrete is a measure of the concrete's ability to resist forces trying to compress or push the concrete together. Concrete is very strong in compression, particularly in comparison to the concrete's strength in tension and flexure which are relatively weak.
