Each Specimen is tested individually in the universal testing machine. The rate of loading should be 140 kg/cm2 per minute. The load is applied until the Specimen fails. Record this load. The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength. P = Load at failure.

Quarried stone normally is delivered to the processing plant by truck and is dumped into a hoppered feeder, usually a vibrating grizzly type, or onto screens, as illustrated in Figure 11.19.2-1. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary crusher.

· 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.
