Recycled bottle glass is chemically known as amorphous silica, which means it contains less than 1 free-silica. free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting media. silica-sand dust in its natural state has an open crystalline structure that has the capability of sticking to lung tissues.
Washed sand comes in coarse, medium, fine and ultra fine granule sizes, of which each size classification requires sand granules that are within a specific diameter range. whatever the size, washed sand isnt necessarily silica sand, and silica sand isnt necessarily washed.

For slab surfaces where extra traction is desired, such as pool decks or sloped driveways, we can create a non-slip finish by broadcasting silica sand, fine glass beads, or other aggregates onto the surface between coating applications. here are just of few of the concrete surfaces you can transform with our acrylic concrete coatings walkways ...
Crushed glass abrasive grit is made from 100 recycled glass. this is an inert abrasive that substitutes for slag and mineral abrasives. it contains no heavy metals, no free silica, and is therefore great for sandblasting projects where it is impractical to recover lost or spilled, spent abrasive.

Glass beads are like the texture of sand, maybe even finer than the sand that you would find on most man-made beaches. it takes a lot less of the glass beads to equal the same weight as the poly pellets, so it makes for a blanket with a lower profile. but because of the texture of sand inside the blanket, it feels very smooth, and doesnt ...
