PolyU researchers introduce biomineralisation as a sustainable strategy against microbial corrosion in marine concrete (IMAGE)
Caption
Characteristics of the development of concrete corrosion in a laboratory seawater corrosion experiment. Panel (a) is a schematic diagram of the seawater corrosion experiment. Panels (b) and (c) are the evolution during the experiment for the concrete specimens with submerged inoculation and the concrete specimens with tidal inoculation. Panels (d) and (e) show the evolution of surface pH during the corrosion for the submerged concrete specimens and the tidal concrete specimens, respectively. The error bar represents the standard deviations (** indicates a highly significant difference, p < 0.01 and * indicates a significant difference, p < 0.05). Note that the SSC in panel (a) is seawater sea sand concrete; Vw and DO refer to the current flow velocity and dissolved oxygen, respectively. The Vw and DO data in this figure were obtained before the corrosion experiment.
