Where does construction aggregate come from?
There are many types of construction aggregate, and as such, many sources for them. However, the sources of aggregates can be grouped into three main categories, which are:
1 – Mining
Many aggregates are mined from mineral deposits. Mined aggregates include sand, gravel, stone, clay, and marl. These are extracted from the earth and may need to undergo industrial processing before they are fit to be used as construction materials.
2 – Manufacture waste
Leftover materials from the manufacture of iron and steel — often called “waste slag” — can be used to make iron and steel aggregate.
3 – Recycling
Concrete, in particular, is often recycled into aggregate. After a building is demolished, the concrete is hauled to a crushing machine — often placed nearby in advance — where its pieces are broken down to form aggregate.
All forms of aggregate need to meet local standards and safety regulations to make sure they are fit for use in construction, as poorly sourced aggregates may compromise the structure of a building.
