Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
The crushing test is conducted using a crushing test machine, applying axial load to the cube at a rate of 140 kg/sq.cm per minute. The crushing strength of the stone per unit area is then determined by dividing the maximum load at which the sample crushes or fails by the area of the bearing face of the specimen.

The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength. P = Load at failure. A = cross-sectional area of bearing face of the specimen. Then the average value of the six specimens is calculated and the result is recorded for that stone sample. You may also like.
