Recycling Concrete Into Crushed Concrete Aggregate: Why It’s the Best Option

The concrete jungles of the urban-bound human race are decaying away. The life expectancy of reinforced concrete structures is not much more than 50 years and deterioration can begin as quickly as 10 years. Megatons of aging reinforced concrete buildings are being torn down every day around the world.

Recycling concrete is a messy and expensive job but a necessary undertaking of any demolition job. Concrete is heavy and there is a lot of it, so what to do with it? How is concrete recycled?

Read on for the low down on the teardown and why aggregate recycled concrete is your best option.

How Recycling Concrete Works

The process begins with breaking out any metal reinforcements and weeding out any pipes, boards, or any other construction material hiding among the rocks. The broken up pieces of concrete are then loaded into rock trucks and hauled to the recycling site.

The concrete is then fed through crushing machines that refine the concrete down to the desired size of aggregate. Various types of heavy machinery do the crushing, including:

  • Jaw and gyratory crushers
  • Vertical and horizontal shaft impactors
  • Compound and cone crushers

The aggregate is then sold back to concrete manufacturers and further refined as needed. The recycled concrete is usually mixed with a fresh aggregate including sand and gravel to create a special blend for mixing up concrete of optimal strength and longevity.

The new mix is bagged, stocked, and shipped off to its new home for the next 50 years as a recycled concrete driveway or highway overpass. The process of concrete recycling seems simple, but there is a whole science to concrete aggregate that dates back thousands of years.

Recycled Concrete Aggregate

Concrete aggregate is the inert filler that compromises 60% to 80% of concrete mixes. Aggregate is mixed with cement to create concrete. Part of the aggregate used for mixing concrete can be recycled concrete powder and gravel.

Recycled concrete is not best suited for certain types of construction requiring the highest possible strength. Recycled concrete aggregate is mostly used for base layers of roads. The benefits of using recycled aggregate are numerous, including:

  • Reducing negative environmental impact
  • Preserving natural resources by reducing mining
  • Reducing cost in the production of concrete
  • Reducing cost in the removal of concrete debris

Concrete is just one of many construction materials we accept.
