What is Construction Aggregate?
Construction aggregate, simply known as aggregate, refers to a collection of granular materials used in construction projects. These materials are mixed together to create a strong and stable base, providing the necessary support for structures and infrastructure developments. Aggregate materials are combined with cement, water, and other additives to create concrete, the most widely used construction material worldwide.

Types of Aggregate
There are various types of construction aggregate, each with distinct characteristics suited for specific purposes in construction:
Crushed Stone
Obtained by crushing larger rocks, crushed stone is the most common and widely used type of aggregate. It comes in different sizes and is ideal for road bases, driveways, and concrete production.
Gravel
Comprising smaller rock fragments, gravel is often used for drainage systems, landscaping, and in the production of concrete.
Sand
The fine granular aggregate is crucial in making mortar, plaster, and concrete, and is also utilized for bedding pipes and leveling surfaces.
Recycled Concrete Aggregate (RCA)
Derived from recycled concrete, RCA reduces the need for new aggregates and minimizes construction waste. It is employed in various applications similar to crushed stone.

Sources of Aggregate
Construction aggregate can be obtained from natural sources or manufactured from recycled materials:
- Natural Sources: Natural aggregate is mined from quarries or collected from riverbeds and shores. Crushed stone, gravel, and sand are commonly extracted from natural deposits.
- Recycled Materials: Construction waste, particularly concrete, can be crushed and processed into recycled concrete aggregate (RCA). This sustainable option reduces the demand for natural aggregates and minimizes landfill waste.

Applications of Aggregate
The applications of construction aggregate are diverse and can be found in numerous infrastructure projects:
- Road Construction: Aggregates serve as the foundation for roads, highways, and airport runways, providing stability, load-bearing capacity, and resistance to wear and tear.
- Concrete Production: Aggregates are a key ingredient in the production of concrete, which is used for buildings, bridges, dams, and various other structures.
- Railway Ballast: For railway tracks, aggregates are used as ballast to distribute the load from trains and maintain track stability.
- Building Foundations: Aggregates form an essential part of building foundations, ensuring stability and preventing settling.
- Drainage Systems: Gravel and crushed stone are employed in drainage systems to promote water flow and prevent erosion.
- Landscaping: Aggregates are used in landscaping projects, such as in gardens, pathways, and decorative features.
