PolyU researchers introduce biomineralisation as a sustainable strategy against microbial corrosion in marine concrete

Caption

Comparison of sulfur levels after corrosion: (a) sulfate on the surface of the concrete; (b) sulfate concentrations in concrete for the submerged groups; and (c) sulfate concentrations in concrete for the tidal groups. Panel (d) is the diffusion coefficient and leaching depth obtained based on the sulfate concentrations at different depths in concrete. After corrosion, the change in the (e) apparent volumes of permeable voids (AVPV), (f) concrete mass, and (g) compressive strength, respectively. Panel (h) is the content of CaCO3 on the surface of the concrete for the specimens with MIC and BCCI. The error bar represents the standard deviations (** indicates a highly significant difference, p < 0.01 and * indicates a significant difference, p < 0.05).
