The Important Role Aggregates Play in Construction

Press Release

All construction projects start with a foundation. No matter what type of construction project you’re completing whether it be a driveway, sidewalk or a parking lot, the foundation of the infrastructure requires the use of high-quality aggregates.

Aggregates are commonly used in the construction of concrete, tiles, steel and other materials. In actual fact, almost 90% of the products used in the construction industry are aggregate based. If we compare this to the use of oil and coal, then it’s easy to see why aggregates are so important.  If you want to learn more about aggregates and the role they play in the construction industry, then keep reading below:

How Aggregates are Used in the Construction Industry

Here are some of the ways aggregates are used in the construction industry:

  • Housing – Approximately 50 tonnes of aggregates are needed to build an average two-bedroom house. Aggregates are needed at almost every stage of the build from the foundations to the roof tiles. The better the aggregates used, the stronger the home will be and the longer it will last. 
  • Paths and driveways – In the last few years, we’ve seen a huge increase in the number of designers choosing to use decorative aggregates in their outdoor projects. A granite manufacturer can produce pre-cast concrete pavers that are perfect for outdoor projects such as paths and driveways. These pre-cast concrete pavers are both aesthetically pleasing and durable and come in a range of colors and sizes to suit your needs. 
  • Buildings and Infrastructure – Almost all buildings in the U.S. (and around the world) were built using aggregates. They are strong and durable, meaning they’re the perfect construction material to use. Aggregates can also be used to make buildings look good. In actual fact specially finished aggregates have been used in a number of architectural landmarks around the world 
  • Roads – Aggregates are used to produce strong, long-lasting roads. They can be altered to provide a resistance to polishing as well as skid-resistance, meaning they are the safest material to use. 

The Features of Aggregate

When it comes to choosing the perfect aggregate for the project, the size, shape and graduation of the aggregate is extremely important. Here’s some of the basics:

  • Size – the size can vary from large tennis-ball sized rocks to small particles like sand. 
  • Shape – the shape of an aggregate can have an impact on what it can be used for. Angular particles are usually tighter and have more friction than rounded particles. This can reduce their workability. 
  • Graduation – the graduation of an aggregate can tell you whether the particles vary in size. Different types of graduation are useful for different projects.

The three main types of graduation you should know are:

  • Poorly graded – this variety has particles that vary in size.
  • Gap graded – this variety is coarse, but the majority of particles are of a similar size to one another. It is usually used to join together the larger and finer aggregates. 
  • Well-graded – this variety comes in a range of sizes from fine to coarse. The particles are all sorted by their size.

Different Types of Aggregates

When it comes to choosing an aggregate for a project, there are a number of different types to choose from. These are some of the most popular types of aggregates used in construction:

  • Sand aggregate- this is the finest aggregate. Sand aggregate is the perfect aggregate for grout and mortar.
  • Gravel aggregate – gravel aggregate isn’t very strong, but it’s fairly cheap to purchase. It is usually used for foundations or in concrete.
  • Granite aggregate – this is a good choice for people wanting to use high-quality materials as it’s extremely strong and durable. It comes in a range of sizes, shapes and colors. 
  • Limestone aggregate – this is commonly used in road construction. It can also be used to re-enforce concrete

In order to maintain a good standard of construction, construction companies need to know about the different resources available to them. Aggregates play an important role in the construction industry and we expect this to continue for many years to come.
