What are the Sources of Natural Aggregates?

Aggregates are the most important constituents in concrete.They give body to the concrete, reduce shrinkage and effect economy. Natural aggregates are inert granular materials such as sand, gravel stone or crushed stone that are used with a binding medium i.e. water, bitumen, portland cement, lime, etc. to form compound materials i.e. asphalt concrete and portland cement concrete.

Basalt Wikipedia

Basalt is an aphanitic (fine-grained) igneous rock that is relatively low in silica and alkali metals.Of its total content of quartz, feldspar, and feldspathoid (QAPF), less than 10% by volume is feldspathoid and less than 20% is quartz, with plagioclase making up at least 65% of its feldspar content. This places basalt in the basalt/andesite field of the QAPF diagram.

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. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as
