Jan 01, 1991 The U.S. Department of Energys Office of Scientific and Technical InformationJan 01, 1991 The U.S. Department of Energys Office of Scientific and Technical InformationAug 08, 2019 Frac sand is named by the size of the grains. The coarsest material standard for frac sand is 2040. This means that 90 percent of the sand is fine enough to pass through a 20 mesh sieve see sieves etc and is coarse enough to be retained on a 40 mesh sieve. As long as your sand meets these requirements, you have 2040 frac sand.Finished Particle Size Regardless the evacuation method, the same factors determine finished particle size.
