DOI: 10.1016/j.cemconres.2017.08.020
Abstract: Abstract This study introduces a novel approach intertwining analytics of spatial microbial distribution with chemical, mineralogical and (micro)structural related aspects in corroded concrete sewer environments. Samples containing up to 4 cm thick corrosion layers were collected… read more here.
