    Recycled Concrete Aggregate - an overview

    Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete. This is largely due to the potential for higher proportions of the masonry

    Concrete recycling is the smart, cost-efficient and environmentally friendly way to reuse aggregate left behind when concrete structures are demolished. Instead of taking up space in landfills, concrete fragments now can be crushed into rubble, which is then sifted, cleaned and efficiently sized into a range of high-quality, standards-approved, competitively priced aggregate materials for a

    Subsequently, a series of concrete batches was produced for evaluating the influence that alternative processing procedures for recycled aggregates have on the main mechanical performance in a fresh and hardened state. Results reported in this paper show the feasibility of "autogenous cleaning", which removes surface impurities and reduces particle heterogeneities, usually characterising

    Strength variation of concrete produced from recycled aggregate is higher than concrete made from natural aggregate. For the recycled aggregate concrete, it would be necessary to add more cement in concrete made with of recycled aggregate in order to achieve the same workability and compression strength as conventional concrete.

    Log washers are used in aggregate processing to remove tough, plastic-type clays from natural and crushed gravel, stone and ore feeds. When in operation, log washers sit at a slope of between zero to 14 degrees, depending on the severity of the washing application. As the percentage of deleterious material increases, the slope must be raised to increase retention time. In some cases, lower

    Recycled concrete can be batched, mixed, transported, placed and compacted in the same manner as conventional concrete. Special care is necessary when using recycled fine aggregate. Only up to 10% to 20% recycled fine aggregate is beneficial. The aggregate should be tested at several substitution rates to determine the optimal rate.
