Concrete Recycling Plant | ELKON

Thanks to ELKON Concrete Recycling Plants which recycle a majority of the waste concrete to be reused, this problem is completely eliminated. By using ELKON Concrete Recycling Plant, the waste concrete released from concrete pump and the truck mixer during washing as well as the concrete left at the truck mixer at the end of a production day can be recycled.

End of life recycling

Recycled concrete can be used as aggregate in new concrete, particularly the coarse portion. When using the recycled concrete as aggregate, the following should be taken into consideration: Recycled concrete as aggregate will typically have higher absorption and lower specific gravity than natural aggregate and will produce concrete with slightly higher drying shrinkage and creep.

Handbook of Recycled Concrete and Demolition Waste

 · High-quality recycling of concrete waste as recycled aggregate concrete is more common in Asia, in particular Japan, than in Europe (Tam, 2009, Tam et al., 2010). Even this so-called high-quality recycling is in most cases still downcycling, as the produced cement has a lower strength, mainly used for non-structural indoor uses.
