Aggregates comprise a combination of loose materials, including crushed stone and sand. These substances can be sourced from quarries and bodies of water and are widely used in residential and commercial projects. Discover some common types of construction aggregates and their uses below. 

What Are Some Common Construction Aggregates & Their Purposes?

1. Gravel

Gravel aggregates include both gravel and scrabbled stone. The key difference is that gravel typically originates from water, while scrabbled stone does not and can be regular or crushed. Concrete, foundations, and road construction are often comprised of gravel aggregates. 

 2. Granite

Used in high-grade concrete, granite aggregate comes in various colors and is often used to add an aesthetic quality in outdoor settings. For this reason, it’s often used for patios. The quartz, feldspar, and mica crystals within the stone determine its color, which can range from grey to red and pink.

3. Limestone

Crushed sedimentary rock is the basis for limestone aggregate. Like granite and gravel, this material is widely used and is often seen in roadway construction. The strong, durable surface created by the stone holds up well against the weight of traffic.

4. Sand

Made from materials such as rock, shells, and coral, sand is coarser than silt yet finer than gravel. It can add stability and bulk to other materials, such as concrete, asphalt, mortar, and cement. It’s also used for decorative purposes on residential and commercial properties.

5. Secondary Aggregate

Secondary aggregates are made by breaking down construction waste, such as brick and concrete. It can be used as a fill for concrete or to stabilize soil. Secondary aggregate can also act as the base layer beneath asphalt and pavement.
