Pure Grit is a mineral slag abrasive derived from copper smelting. This copper grit is sharp, hard, durable and contains less than .5% of free silica.
In conventional blasting equipment, pure grit can replace traditional silica sand. Typical applications include: ships, bridges, concrete, storage tanks, structural steel and castings.
"Cutting effectiveness, low dust and overall value have made Shaw's Pure Grit the dominant non-silica abrasive in the Atlantic Canada market."
