Abstract: Abstract Portland-cement based concrete samples were incubated for 28 days (short-term) in microbially derived H2SO4 (pH 1.3–2.4) and chemically generated H2SO4 (pH 1.0 and 2.0) to investigate potential differences between the two acid attacks. Additionally, long-term biogenic experiments… read more here.

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.

DOI: 10.3390/ma15124279
Abstract: Microbiologically induced concrete corrosion (in wastewater pipes) occurs mainly because of the diffusion of aggressive solutions and in situ production of sulfuric acid by microorganisms. The prevention of concrete biocorrosion usually requires modification of the… read more here.
