Construction aggregate - Wikipedia

Construction aggregate, or simply aggregate , is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.Wyoming’s Construction Aggregate Resource,production was apparently impacted but the market quickly rebounded in 2009 with a high of more than 34 million tonnes, valued at $170 million, according to the USGS.Powder River Basin - Homepage, USGS: Energy,Using a geology-based assessment methodology, the U.S. Geological Survey estimated in-place resources of 1.07 trillion short tons of coal in the Powder River Basin, Wyoming and Montana.
