② How Does Aggregates Come From?
Primary aggregates are produced from natural sources, extracted from quarries, sand & gravel extraction sites, and in some countries’ sea dredged. Secondary aggregates include recycled and re-used aggregates. Recycled aggregates are reprocessed materials previously used in construction. Manufactured aggregates are usually by-products of other industrial processes such as blast or electric furnace slags or china clay residues. (Usually Crushed by Jaw, Cone and Vertical Shaft Impact Crusher, Myloo carbide wear parts prolong the lifetime of crushers)
③What Is Aggregates Used For?
Aggregates are granular materials used in construction our roads, sidewalks, buildings as well as railway ballast, armour stones, beach replenishment,etc.. It’s in virtually all of our construction materials-asphalt, concrete, glass, brick etc.. Aggregates are also raw materials used in the manufacture of other vital construction products such as ready mixed concrete (made of 80% aggregates), pre-cast concrete products, and asphalt products (made of 95% aggregates).
Knowing about our reliance on aggregates for constructing helps us appreciate how fortunate we are to live on our unique rocky planet. It also helps us ensure that we use these earth resources sustainably.
