Silica Pebble
Silica pebble is a relatively new application of white to gray silica gravel. Several size ranges are available and, depending upon the size, applications include loose decorative gravel, and decorative driveways and pool decks where it is embedded in epoxy resin over concrete. Very high silica white pebble is crushed and finds applications in decorative gunite in swimming pools and as white roofing granules. Sheridan White Rock Company in Grant County, Arkansas, produces both bagged and bulk shipped silica pebble. Their mine is located 11 miles south of Sheridan. Production is withheld to avoid disclosing company proprietary data.
