What Is Frac Sand? "Frac sand" is a high-purity quartz sand with very durable and very round grains. It is a crush-resistant material produced for use by the petroleum industry. It is used in the hydraulic fracturing process (known as "fracking") to produce petroleum fluids, such as oil, natural gas, and natural gas liquids from rock units that lack adequate pore space for these fluids to flow ...

Crush Resistance – The measure of the strength of a mass of screened, fines-free dry proppant to force applied over a fixed cross-sectional area, providing an equivalent stress to the proppant under test. The mass of proppant introduced to the crush cylinder is a function of its Bulk Density and the specified loading of 4.0 lb/cu ft.

Abrasion Resistance. This is a consideration in wastewater rising/force mains in which there are solids transported with the water and pump operation sequences can result in solids rubbing along the pipe invert. PE100 has the best abrasion resistance of the commonly used pressure pipe materials. This is illustrated in the Figure below.

The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke''s law.Hence, for this region, =, where, this time, E refers to the Young''s Modulus for compression this region, the material deforms elastically and returns to its original length when the stress is removed.

Bulk Density ($75) – This is required in order to perform crush resistance testing. The bulk density describes the mass of material that fills a unit volume and is used to determine the mass of material needed to fill a storage tank. In this case the bulk density determines the amount of material to use in the crush resistance testing procedure.

Crush Resistance Testing Crush resistance testing involves the measurement of a compressive load to a point when a sample deforms, fractures, shatters or collapses. This type of test may be applied to a variety of products including corrugated cardboard, glass, bearings, bricks, concrete, or any sample where crush resistance is important.

Compressive Strength. EPS is a closed cell, lightweight and resilient, foamed plastic composed of hydrogen and carbon atoms. The mechanical strength of EPS varies with its density. The most important mechanical property of EPS insulation and building products is its resistance to compressive stresses, which increase as the density becomes higher.
