What are the 4 main types of aggregate materials?

Aggregates are important materials for residential and commercial construction projects. They are gotten from quarries, pits, and even sea materials in some countries. The main types of aggregate materials are:

Granite aggregates: Granite aggregate are regarded as the best for high-grade concrete. It is available in various shades such as pink, red, and grey. Granite consists of quartz, feldspar, and mica crystals which play a major part in determining the color of the stone.

Limestone aggregates: Limestone aggregates are majorly used for road construction and reinforced concrete. They are made through grinding and crushing of sedimentary rocks.

Gravel aggregates: Gravel aggregates can be gotten from the crushing of natural stone and sifting quarried rocks. They have low radioactive content and are great for foundations and concretes.

Sand: Sand is an aggregate material that is used in products  like asphalt and concrete for increased bulk strength. It combines with water and other aggregates to form concrete which is used in various construction applications.
