Aggregate is one of the most mined materials in the world, with multiple uses. Sand Shifters, in particular, is an Aggregate supplier of top quality recycled and non-recycled Aggregates for the construction industry - with many valuable and practical uses as a raw material that you may not even know about.
Here are the top 8 uses of aggregate:
1. Concrete:
Mixed with cement and water to form concrete, in order to create a strong paste. Used for building foundations, walls, pillars, bridges and many more.
2. Construction:
Used in construction to protect pipes by surrounding them with aggregate to protect the pipe from sharp objects, to fill voids from soil that was removed, create hard surfaces and drainage.
3. Mortar:
In order to bond bricks or to provide weather protection, an aggregate is used in mortar along with sand, cement, and water.
4. Filtration:
Generally consisting of sand, gravel and crushed rock, aggregate used in water filtration is a great way to ensure clean, quality water by getting rid of unwanted elements.
5. Railway ballast:
In order to support the weight of a train and to protect the ground underneath, a good quality aggregate is used - consisting usually of large granite pieces.
6. Asphalt:
Used as a base for constructing pavements, roads, parking areas and even playgrounds - to create strength and stiffness, and mixed with binder and a filler to create asphalt.
7. Roofing:
Used in roofing for sustainability, reflectivity, and insulation, a mineral aggregate is added to protect the asphalt layers and shield from UV rays. They come in different colours and shapes to suit the roof type.
8. Ice road control:
Not particularly pertaining to South Africa, but an interesting use none the less. Used for ice road control in a lightweight aggregate form, it prevents vehicle skidding or hazardous roads as well as sidewalks to prevent unnecessary falls.
