The sample preparation and testing method are easy in the crushability test. A small amount (500 g) of crushed rock is enough for testing. This is an advantage when there are limited rock samples. That the crushability test can be applied on the drill cuttings is another important advantage.

Rock is the most used natural resource in the world. The two main types of natural aggregates are 1) crushed rock and 2) sand and gravel. As a main ingredient in asphalt and concrete, these aggregates are used in the construction of highways and bridges, as well as in both residential and nonresidential buildings.

Crush rock samples using large jaw crusher (if necessary), then use small jaw crusher until particles are pea sized. Homogenize. Crush pea-size sample in tungsten carbide disc grinder (hockey puck) to approx. 100 mesh (feels like talcum powder between fingers). Homogenize sample using cone and quartering techniques.

The efficacy of crushed-rock samples vs. small plugs or full-diameter core samples for measurement of porosity, permeability, and fluid saturation is an important consideration in the evaluation of tight-gas reservoirs and shale-gas reservoirs.
