What Are The 4 Main Types of Aggregates?

“Aggregates are small rocks that are used in construction. Sand, gravel, crushed stone, and recycled concrete or fill are the primary materials. These different materials are used to hold the ingredients together so that they can be used in various landscaping projects. In detail, let’s look at each aggregate.”

Why Use Aggregates In Construction?

Strength and Durability

Aggregates provide strength to concrete. The final product can reach its full potential. Without aggregates, the material might not be able to handle the weight placed on top of it or be able to last in high traffic areas without cracking.


Aggregates can be used to enhance the final product. Aggregates can be chosen to match up with the environment.


Aggregates tend to be readily available in most parts of the country, making them accessible to contractors. Moreover, there are several aggregate suppliers available who can provide material to projects if required.

Environmentally Friendly

“Chunks break off larger rocks as they weather away. It’s a natural element that doesn’t require a lot of energy to produce, compared to steel or plastic.”


Aggregates are cheap and durable and can last a long time. In the long run, that saves money for contractors and clients.

The 4 Main Types Of Aggregates and Their Different Properties


Sand is a common fine-grained sedimentary material made from fragments of rocks or minerals, including quartz.   Typically used in mortar and concrete mixes due to its round particles that are easy to mix. Comes in different forms, including ordinary sand, coarse sand, and fine sand.


Gravel is a common coarse-grained sedimentary material with a particle size ranging from 0.4 inches to 2 inches in diameter. Is typically used for medium to large-sized aggregates in the construction industry.

Gravel can be found in two forms: pea gravel and crushed stone. They have an even shape, and they are suitable for heavy-duty projects, including driveways or roads that will need to handle high traffic volume or heavier loads.

Crushed Stone

Crushed stone is a more processed (version of gravel) aggregates comprising of angular or subrounded particles. Is mainly used for medium to large-scale projects and is often found in major commercial building sites since it can handle heavy traffic.

There are different shapes of crushed stone, ranging in size from 2 inches to 3 inches.


Ready Mix Concrete Essex is a mixture of cement, aggregates, sand, and water forming solid materials suitable for building roads, buildings, or pavements.  Concrete is formed under high pressure by mixing the ingredients, which explains its excellent texture.

In landscaping projects, concrete can be used in various forms; ready mix, bagged concrete, and unbagged concrete.

Which Types of Aggregate Are Right for Your Project?

The best aggregate for your project will depend on its goals, expected results, and anticipated lifespan. In addition to landscaping, pea gravel can be used for quick projects.
For long-term projects, crushed stones are the best choice. They have a heavy-duty design.
