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 deterioration of concrete.
Crushed Stone. Crushed stone is used as aggregate in construction material uses. The most common types of rock processed into crushed stone include limestone, dolomite, granite, and traprock. Smaller amounts of marble, slate, sandstone, quartzite, and volcanic cinder are also used as construction aggregates. Other Industrial Material.

Indiana Limestone is a freestone, which means that it exhibits no preferential direction of splitting and can, therefore, be cut and carved in an almost limitless variety of shapes and sizes. This property allows the stone to be planed, turned on a lathe, sawed, and hand worked to match the requirements of the most demanding architectural designs.
