0 to 4mm sharp sand
Sharp sand, also known grit sand or concrete sand, is the largest size of sand available at the Brewster Brothers recycling plant.
Where does it come from?
Sharp sand can be found within the construction and demolition waste that is processed at our recycling plant. We are a circular business, recovering and regenerating waste to minimize the impact on the environment. Regenerating waste from the construction, demolition and excavation industries allows us to extract the maximum value from the aggregates which keeps them in circulation for as long as possible. Virgin aggregates like sand are in limited supply, which is no surprise because they’re core building resources. Using recycled aggregates reduces the demand for these finite resources benefiting the environment. The linear take, make, dispose model isn’t sustainable and has already had a serious impact on the environment.
How do we separate and produce our sharp sand?
- Waste from construction and demolition sites is fed into our state-of-the-art wash plant.
- All oversized objects (anything more than 100mm) are removed.
- Any metals that weren’t removed during the primary screening are extracted using a large magnet.
- As the waste moves through the plant, it is washed and screened to separate it into the different types and sizes of aggregates.
- Anything below 4mm is sent through to the sand plant where the hydrocyclones use centrifugal force to separate out the two types of sand.
- At this point the sand is segregated based on its density and cut to produce 0-4mm sharp and 0-2mm soft sand. The two types of sand are then fed into their respective stockpiles.
Applications and uses
for sharp sand
Sharp sand is used for its gritty properties. The rough texture and angular shape of sharp sand helps it to bind well with other ingredients, making it an ideal component in concrete production or for laying slabs and mono bricks.
