Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...

Operations Overview. The aggregate mining process involves removing aggregate source materials from different depths of the earth's surface. The first eight to ten feet of material, called overburden, is removed using an excavator. The next 20 to 25 feet of excavation material is rock material consisting of coral limestone and limestone.

A controlled explosion is normally used to release the rock from the working face. It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening stages to produce a range of final sizes to suit customers' needs. Just enough explosive is used in blasting to break the rock from the face.

Aggregate materials are either used in their natural state or after crushing, washing, and sizing. The materials can be used loosely, or sand, gravel, and crushed stone can be combined with a binding media to form concrete, mortar or asphalt. The mining process begins with the removal of the overburden to reveal the materials underneath.
