Construction aggregates are used widely in the building trade, and they’re a vital part of building materials, providing foundation support to projects. Construction aggregates are made out of materials that include gravel, sand and crushed stone, which are then combined with cement and other binding agents to make concrete or asphalt.

What types of aggregates are there?
The materials that create aggregates come from natural sources in gravel pits, quarries and rivers. They’re widely available and affordable, and include sand and gravel.
How are aggregates combined to make building materials?
Sand is used to make concrete and mortar. Concrete is made by binding cement and sand with coarse aggregates. Sand and cement can also be used to make building mortar. Aggregate is used in other ways, too. For example, crushed stone is used for railway ballast and road building, as well as for landscaping.
Can aggregate be recycled?
Yes, and Recycled Concrete Aggregate or RCA – is used for road building, backfilling, to create new concrete and to make pavements. It’s an important way of creating circular building materials that are more sustainable and reducing waste in construction, which is a vital goal in construction sustainability, especially when mineral sources are ultimately limited.
