Recycling concrete is a process of breaking, removing and crushing it from its current location. It is then re-created to be good as new. It is often the best option for concrete removal. Even just a slab of concrete doesn’t make any difference all recycled concrete is aggregated for using subbase material. It can also be paired with new and

Concrete with compressive strength of 60 MPa were crushed by applying three methods: RC-1, recycled concrete aggregate from concrete waste by one-time jaw-crushing before being screened; RC-2, recycled concrete aggregate by ten-time jaw-crushing before being screened and RC-3, recycled concrete aggregate produced from three consecutive crushing processes using a Smart Crusher.

Each batch of recycled concrete is going to have a certain amount of different aggregate types based on how it’s crushed and its original components. As a result, for large-scale jobs with minimal time, you may want to try and get original concrete you can have made to order.

Using recycled concrete saves both the environment and money. As mentioned above, with recycling we can consume less raw materials and preserve gravel resources. Also, depending on the chosen equipment, there can be less transportation needs, which means lower fuel consumption. For example, with mobile crushers, crushing can be done

As far as recycling is concerned, asphalt and concrete are among the simplest materials to recycle and re-use, with significant markets available for recycled aggregate. According to the U.S. Geological Survey Fact Sheet on Recycled Aggregates , more than 100 million tons of asphalt is recovered annually in the United States, with 80% of it being recycled (the other 20% still goes to landfills).

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Recycled aggregates are only classified as recycled concrete aggregates (RCA) when the primary material is concrete. By crushing and compressing existing waste concrete and combining it with aggregate, producers can create concrete aggregate to a specific size and quality, which makes it very cost effective to purchase.
