Scanning electron microscopy views of MICP treated Blessington sand: (A) Presence of microbes (shown in orange color) on the surface and within the calcite crystals, (B) Morphology of precipitated calcite crystals on the surface of a soil particle, (C) Muscovite particle cemented between two other soil particles, (D) Larger, blocky calcite crystals in the cemented samples (E) Aragonite polymorph and cemented soil particles, and (F) Low magnification view showing a representative view of cemented soil unit: widespread precipitated calcite crystals, cementation bonds and matrix, and calcium carbonate polymorphs.
