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 reinforcement to add strength to the overall composite material. Due to the high pressures exerted during compacting operations, Aggregates are also used as a base layer for roads and railways.
In addition, aggregates are used in drainage applications and as pipe bedding material. As a filler or extender in various products such as paints, plastics, ceramic tiles and cosmetics.
Types of Aggregate
There are two main types of aggregates: natural and manufactured. Natural aggregates are extracted from rock formations through blasting or drilling and include sand, gravel, and crushed stone. Manufactured aggregates include recycled materials such as glass, asphalt, or concrete.
Common Aggregate Uses
The most common use for natural aggregates is in the construction of roads, railways, and building foundations. The majority of manufactured aggregates are used in the production of concrete for the construction of infrastructure such as office blocks, bridges, dams, and homes.
Other uses for aggregates include drainage applications such as septic systems and French drains, as well as pipe bedding material to support underground utility pipes. In addition, aggregates are often used as a filler or extender in various products such as paints, plastics, ceramic tiles and cosmetics.
There are many different types of aggregate that can be used for construction purposes. The most common type is gravel, which is typically composed of small pieces of rock that have been crushed. Other types include sand, slag, and crushed stone. Each type has unique characteristics that make it ideal for specific uses.
Gravel Aggregate
Gravel is the most common type of aggregate because it is inexpensive and easy to find. It is also easy to work with, making it a popular choice for construction projects. Gravel can be used in a variety of applications including driveways, pathways, and as a base layer for roads and railways.
Sand Aggregate
Sand is another common type of aggregate that can be used in a variety of applications. It is often used as a base layer for paving projects such as driveways, roads, and patios. Sand is also commonly used in the production of concrete.
Slag Aggregate
Slag is a by-product of the steelmaking process that can be used as an aggregate in construction projects. It is typically used as a base layer for roads and railways.
Crushed Aggregate
Crushed stone is another type of aggregate that can be used for construction purposes. It is typically made from granite or limestone and is widely used in the construction of roads, buildings, and bridges.
Aggregates are an essential component of construction projects. They are versatile materials that can be used in a variety of applications. Whether you are looking for gravel for your driveway or slag for your railway project, there is an aggregate that will suit your needs.
