Recycling concrete is an important process when considering environmental health. Recycling concrete helps to preserve natural resources and prevents the unneeded waste of concrete. Concrete is re-purposed as aggregate material for foundations, walls, road construction projects and more. With the exception of the poorest quality of concrete, most concrete crushes pass rigorous quality tests to prove durable.
The Recycled Aggregate Process
When using recycled aggregates in concrete, the original aggregate material is mixed with hydrated cement paste, which is added in order to increase the porosity of the mix, as well as the specific gravity. After a removal process by which contaminants are extracted from the aggregate mix through selective demolition, air separation and size reduction, the concrete can be used for more structural applications such as bridge foundations, curbs, and gutters.
Ways in which recycled aggregates in concrete can be used without any procession include: a wide range of general bulk fills, noise barriers along the sides of highways, road construction, bank protection. Most unprocessed concrete aggregate is sold crushed as 1 and a half to 2-inch fractions, for pavement subbases.
Grit is the finest of crushed stones, used to improve traction on roads, and for walking. It is used to keep icy roads from becoming too slick and is often put in patios to add a layer of coating. Gravel is used for yard paths and can be ordered in your color choice.
