Recycled concrete can also be used for paving stones, water features, retaining walls, rock walls, and underpass abutment structures. Concrete recycling is the use of rubble from demolished concrete structures. Any metal pieces, contaminants, or debris are removed from the concrete aggregate so that it is pure in its composition. Concrete pavement recycling is a relatively simple process that involves breaking, removing and crush ­ing hardened concrete from an acceptable source to produce recycled concrete aggregate (RCA), a gran ­ular material that can be produced for any application for which virgin aggregate might be used. Landscaping mulch: When properly crushed and well sorted, ground concrete can replace river rock or other gravels used as ground covers and mulch. Crushed concrete can be used as an aggregate in ready-mix concrete, replacing some of the new (virgin) aggregate that is typically used. The material is then screened and where required blended to produce a range of recycled products. 1. Old concrete can be reused for: Broken concrete creates a permeable (porous) pavement surface so water can filter through and replenish groundwater instead of becoming stormwater runoff that contaminates waterways.

Here is a breakdown on how to recycle concrete: To recycle concrete, the concrete must first be broken and removed from the existing pavement—i.e., the demolition of concrete foundations, driveways, sidewalks, and other concrete structures. And concrete makes up the most significant part of this waste—about 70 percent of C&D waste before recycling. 6 In general, applications without any processing include: 1. many types of general bulk fills 2. bank protection 3. base or fill for drainage structures 4. road construction 5. noise barriers and embankments Most of the unprocessed crushed concrete aggregate is sold as 1½ inches or 2 inches fraction for pavement subbases. As an aggregate sub-grade, recycled concrete can stabilize soil with its load-bearing capacity. Typically used in a recycling yard where all material is trucked to the site. Enviro-Port manufactures the world’s highest quality, most durable and most dependable concrete reclaimer and Ready-Mix Recycling systems for the ready-mix and precast industries. Concrete is recycled by using industrial crushing equipment with jaws and large impactors. Concrete recyclers will then haul concrete from a demolition site to a concrete recycling plant. These processes include handpicking, electromagnetic separators, air separators, and water flotation separators. Bed foundation material for trenches containing underground utility lines: Utility trenches are oven covered with gravel to assist drainage, and crushed concrete makes a good, inexpensive substitute for gravel. Others suggest to pulverize the waste concrete but doing so makes it harder to separate the unnecessary components and to control the particle size distribution. Job requirements - 30" minus concrete on a demo site to be reduced to 1-1/2" minus base material. However, when it comes to the need to dispose of concrete waste from your work site, concrete recycling in Baltimore can make the daunting removal process much more efficient. Instead of mining and transporting new aggregates for concrete production, recycled concrete can be used in its place, cutting down on energy use and fuel emissions involved in sourcing and transporting other aggregates.
