Recycling Solid Concrete: Solid concrete that has been demolished can be recycled on site or at a plant. Machines crush or grind the concrete up into small aggregate that are then used as a base material or to make new concrete.
Cost to produce recycled concrete aggregate range from £5 to £12 per tonne. The cost depends on the quantity, the quality of demolished concrete, and the size and type of plant being used. Lowest cost comes from large quantities of demolished concrete using high output plant and machinery.
One of the main reasons for scepticism towards recycled aggregate concrete is the perceived notion that the heterogeneity of recycled aggregates may increase the uncertainty of the behaviour of concrete. Therefore, the paper uses structural reliability concepts to propose partial factors for recycled aggregate concrete's design for shear failure.
For that reason, we recycle concrete with crushing equipment into a number of products from pipe bedding to riprap. The concrete which came out of a demolition project, is diverted from the landfill and turned into a useful product requiring little processing, saving energy and natural resources.
