Microbial carbonate precipitation for the improvement of quality of recycled aggregates
Journal of Cleaner Production, 2017 High water absorption is the main drawback of recycled aggregates which greatly hinders the re-use of them in concrete production. In this study, bio-deposition treatment, based on bacterially induced CaCO3 precipitation, was applied to improve the ...
