### compressive strength of concrete test

### Compressive Strength

Compressive strength is most often measured by forming 150 mm diameter, 300 mm long 6 inch diameter, 12 inches long test cylinders and then breaking them at a specified age typically 28 days although it can also be performed on specimens of different sizes and origins such as field cores or the remnants of a flexural test...
