The resulting recycled concrete can be used for various construction applications, such as road bases, sidewalks, and structural elements. Other Applications: Recycled concrete can also be used for other purposes. For instance, it can be crushed into smaller sizes and used as fill material for landscaping, erosion control, or as a base for new ...

 — Sika has developed a highly efficient process to separate and reuse demolished concrete components while increasing the quality of recycled aggregates.

 — For full incorporation of coarse recycled concrete aggregates and the design of elements without shear reinforcement, the calibrated partial factor reduces the design value of shear resistance by 10% (design with EN1992) or 15% (design with prEN1992) in comparison to natural aggregate concrete's design.

 — Recycled concrete not only stays out of landfills, but it also replaces other materials such as gravel that must otherwise be mined and transported for use. Benefits of Concrete Recycling . Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces ...

Concrete has been the rock star of modern architecture: it is strong, versatile, and durable, able to withstand natural and environmental disasters.However, it has a downside: it is highly contaminating, one of the leading causes of CO 2 emissions and debris, not to mention its financial cost. Fortunately, the advances in technology have taken us very …

Recycling concrete is an important cost saving strategy when your business generates concrete waste. Demolished concrete can be treated to ensure the material carries no contaminants, and unused concrete can be crushed and repurposed at the job site. This reduces the demand for new concrete production, adds efficiency in material preparation ...
