Aggregate in Deal | Why Do We Put Aggregates in Concrete?


Concrete is one of the most common materials found in our towns and cities. Yet, those outside of the aggregate supply, muckaway and grab hire trade don’t know an awful lot about it. For example, did you know that, whether manufactured, natural or recycled, aggregate plays a crucial role in the creation and performance of concrete?


As aggregate suppliers serving Deal and the wider Kent areas, we enjoy taking the time to explain aspects of our industry. Because we cover everything from land restoration to grab hire services, our work often involves the collection of broken and smashed concrete as well as the delivery of materials to mix new batches.


First, let’s get a better understanding of the term ‘aggregate.’

What is Aggregate?


This term covers a wide range of particulate matter. Examples include crushed stone, sand, slag, gravel, recycled concrete and geosynthetic aggregates.


Aggregate accounts for roughly 60% to 80% of concrete’s volume, and 75% to 80% of its weight. In fact, this is why aggregate is sometimes referred to as ‘filler’.


As any aggregate suppliers will confirm, ‘filler’ doesn’t do this material justice. Some of the most premium concrete around originates from the presence of aggregate. These all have impressive elastic and thermal properties and dimensional stability.


The Role of Aggregate in Concrete




As with so many aspects of land restoration, muckaway, grab hire and construction work in Deal, cost plays a huge role in concrete manufacturing. Aggregate represents the highest proportion of any other ingredient in concrete, but also the least expensive. As such, you can easily calculate the economic impact of using the material.


Naturally, you can lower the cost of concrete by altering the ratio of aggregate used. What’s more, you can also select large, coarse aggregate to lower costs as it reduces cement (the costliest ingredient) requirements.




Certain types of construction must possess aesthetic as well as practical qualities. If your land restoration, landscaping or building work in Deal has exposed concrete, aggregate helps to create a visually appealing look.


Our aggregate suppliers provide you with materials that can alter the colour, texture and shape of your concrete. Limestone, marble, basalt, granite and quartz all make popular choices for exposed concrete. As a muckaway and grab hire company, we can supply whichever material you require.




You can work with our aggregate suppliers to choose materials that create a certain shape and texture for your concrete. This, in turn, alters its workability. For example, smooth, rounded aggregate makes concrete much more workable. In contrast, angular, rough or elongated materials create a much less adaptable product.


You may also prefer smooth, rounded aggregate for your concrete because it requires less cement. Angular, elongated products – usually crushed stone from our own muckaway and grab hire collections in and around Deal – require much more cement to create a workable mixture. Of course, this makes it more expensive.


However, the latter option is more desirable for its bond characteristics and high surface-to-volume ratios.
