Aggregates are a component of concrete and have been used to make it for hundreds of years along with asphalt. Base layers for roads and foundation for buildings all use aggregates. They are also used in DIY projects and domestic projects for decorative purposes and can be bulk bagged for ease.
Aggregates are available in many different grades and textures and the aggregate you choose depends on the job you need it for. Here we will look at different aggregates and what their uses are to give you an insight into the best aggregate to choose for your projects.
Sand – This is the most popular and basic form of aggregate. Sand is created naturally by erosion or can be quarried. Sand is usually brown, grey, or cream in colour. Sand also comes in different forms including ballast, sharp and recycled. Sharp sand is suited for paving concrete as it has large grains. Ballast sand is mixed with gravel and is used in foundations and roads as it is heavier.
Gravel- Gravel is larger than sand and is used within pavements and driveways it can be mixed with concrete but is often used alone. Gravel is used in landscaping projects as it will help stop weeds and grass growing through.
Rocks and pebbles- Rocks and pebbles come in all shapes and sizes and even colours and are mainly used for decorative purposes.
Crushed Rock – Crushed rock is simply crushed rocks to make them smaller. It is used in concrete slabs and driveways.
Recycled aggregates – Recycled aggregates include recycled sand which is from washed away concrete or masonry. It is used in mixes and block paving. Recycled concrete saves on costs and is crushed down and used in base layers.
Sub Based Aggregates – These are made from recycled concrete and rock limestone and are very commonly used in pavements for strength and durability.
