Crush resistance is typically measured using the K-value or crush resistance test. The higher the K-value, the more crush-resistant the sand is. Frac sand with a K-value of 8,000 psi or higher is considered …
How To Crush Frac Sand – Part 2
When I have trained lab technicians, this is usually the step that causes their crush test results to go awry — not taking the time to build a perfectly level "disc" of sand in the bottom of the cylinder. Here's our professional actor turned lab director (ha) in action on Part 2 of the Frac Sand Crush Test Saga:

Grain breakage criteria for discrete element models of sand …
Frac sand consisting of quartz grains is widely used in hydraulic fracturing of tight shales to prop fractures open. However, the sand can be crushed by high compressive stress acting on the fractures and this reduces the fracture conductivity. In practice, a one-dimensional compression test is widely used to evaluate the crushing resistance of frac …

QUALIFYING FLUID & PROPPANT
is similar to that of 40/70 frac sand public data. Figures 1 & 2 The ISO Crush requires that crush properties of a proppant are evaluated at incremental pressures until fines generated are < 10% by weight. For the Southern Ohio Sand 40/70 Sand the crush test was halted @ 6,000 psi with the sample producing an average of 9.5% fines.
