Releasing Quartz Crystals from Sandstone
Natural Sand is in great demand as the key ingredient for concrete and asphalt. Traditionally it has been derived from natural rivers, streams, estuaries or dune deposits. After centuries of use, sand around the world is now in limited supply.
Rock Trade Industries has discovered the process to release quartz crystals, that is natural sand, from sandstone through advanced manufacturing technologies and processes.
Petrographic tests have determined this material to be clean, medium, grained natural lithic quartzose sand. It is classed as a premium product and is in high demand by the asphalt and concrete industries.
Queensland’s Department of Transport and Main Roads has approved this product as a natural sand and has granted approval for its use in concrete and asphalt as a 2.36mm fine aggregate.
