Properties of recycled concrete Recycled concrete meets the same requirements as traditional concrete. The strength, viscosity and quality match those of natural aggregate concrete, so recycled concrete is just as easy to work with. Recycled concrete is available up to strength class C30/37, lower strength classes are approved for frost periods. Overview of the main advantages of recycled concrete: The use of recycled concrete reduces the consumption of natural resources by nearly 30% . Standard specifications for construction project tenders include options for the use of recycled concrete.récupération de béton All construction projects up to a strength of C30/37 can be made with recycled concrete. European standards limit it to 30% in structures (bearing elements, wall type), or even 20% on the insurers' side. The possibility of increasing the percentage allowed is currently being researched. The Belgian standard NBN B 15-001:2018 limits the rate of substitution by recycled aggregates to 50% in the best case, i.e. for the production of class X0, XC1 or XC2 concrete. The CE marking does not replace the NBN mention for aggregates. Aggregates producers have set up quality assurance systems for their operational practices that certify their production (voluntary certification – NBN mark – aggregates). This mark makes it possible to certify, by more rigorous controls and tests complementary to those of the CE mark, that the aggregates comply with the standards NBN EN 206 and NBN B15-001 for the general characteristics of aggregates and with the standard NBN EN 12620. for the mechanical and physical characteristics of the aggregates. The prerequisite for recycling concrete is that the materials are sorted by type, so it is important to treat them strictly separately from each other. Besides classic masonry, tiles can also be recycled. If construction waste contains metal bars, pieces of wood or plastic, they are disposed of during the production process. A special sieve in the bucket of a wheel loader separates the bricks or stones from the remains of plaster, pieces of wood or plastic film, so that the rubble can then be crushed. First, a hydro-chisel coarsely grinds the material before finely grinding it in the "crusher" to a particle size of 60 millimetres. A screening plant divides the crushed particles into aggregates of different diameters. Mixed with water, cement and possibly other additives, the aggregate is transformed into a material that is easy to implement and respectful of the environment: recycled concrete.

Disposal and recycling of renovation debris 1-800-GOT-JUNK? is the largest and most trusted junk removal company in the world, and has been providing our quality services since 1989. We also offer construction cleaning services for businesses. Thanks to our experience and reliability, building materials and scraps disappear very quickly! Concrete If you are managing a renovation project and you need to redo the foundations, you will surely have to get rid of excess concrete. The price varies a bit for concrete collection since it is not billed by volume, due to weight restrictions in our trucks. We make sure to talk to you about it during the scheduled appointment. Recycling concrete helps minimize the environmental cost of extracting virgin aggregates, such as stone and gravel. Excess concrete from construction sites can be reshaped into crushed stone, conserving natural resources and avoiding unnecessary filling of landfills.
