Why do we use aggregates in concrete?

Aggregates play a very crucial role in the process of making concrete- whether they are the manufactured, recycled or natural filler in concrete, they account for approximately 60 to 80% of its weight.

So why are aggregates so useful in concrete?

Firstly, they are extremely cost-effective, the proportion of them in concrete if the highest out of anything else and is the least expensive material used. That is because a lot of aggregates are recycled and therefore they are cheaper materials to use. Not many people know this but the cement is the most expensive component in a concrete mixture, meaning that you can easily change the final cost of the concrete by changing the ratio of the aggregate used- if you need to make your project cheaper.

What’s more, aggregates can affect the aesthetic outcome of a project, as the term is a general word for different materials such as sand, stone and gravel, all of which differ in colour, shape and texture. In some projects, exposed-aggregate concrete is used to give a different and pleasing appearance, with natural stones being perfect for such uses.

In addition to this, aggregates have been proven to offer additional volume stability to a concrete mixture that has hardened, which works in the favor of the builder as aggregates will stop the possibility of cracks.
