Environmental Considerations in Concrete Recycling
Mar 29, 2017• RCA concrete tends to leach higher levels of metals than conventional concrete • Leachability of metals depends on type of metal, pH, carbonation, and mobility characteristics (Galvin et al. 2014) 27 Use of RCA in concrete mixtures mitigates water quality issues associated with leaching.
