Sand aggregates used in making hollow blocks can be replaced with quarry dust. By using proper ratio of quarry dust with regular clay, fired bricks with improved strength can be manufactured.
When used for construction mortar, the refined crusher dust without micro fines below 150 micron contributes the maximum compressive strength when compared to sand and unrefined dust.
Rock dust is either used as a clay substitute, or a sand substitute to make tiles.
Rock dust is used as sand substitute for concrete roads. It can also be used as a mineral filler along with larger metal, on asphalt roads.
Fine rock dust can be used as a clay substitute for stoneware pipes. These pipes are used in plumbing, irrigation, and for drinking water. They are non-toxic, do not wear down or corrode, and are long lasting.
