Optical Microscopy Imaging of Muskeg and Reinforced Composites. Stereomicroscopy images of (a) unmodified and (b‒f) modified muskeg with different concentrations of added Na₂SiO₃ and mulch: (b) 20 mL and 10 g; (c) 20 mL and 5 g; (d) 20 mL and 15 g; (e) 30 mL and 5 g; and (f) 30 mL and 15 g. The amount of NH₄OH and hydroxyethylcellulose were held constant for each modified muskeg specimen at 10 mL and 2 g, respectively. Scale bar = 1 mm.
