    Garnet (granat sand) is a hard silicate mineral quarried in several parts of the world, including Australia, India, the USA and South Africa. There are some eight different forms of garnet but the one most commonly used for abrasive blasting is almandite garnet which is an iron-based material. It is very heavy, very hard, very abrasive and durable.

  • The effects of spent garnet in high strength concrete

    The ability of garnet to be recycled makes garnet suitable for many industrial purposes. When the recycled garnet can no longer be reused in the ship cleaning process, garnet is removed from the shipyards and named as "spent garnet". This has resulted in millions of tons of spent garnet disposed in landfill, quarries, oceans and rivers, thus causing environmental problems.
