Table 1 Densification of Modified Muskeg Composites as a Function of Composition. Measured density of muskeg samples modified using a fixed amount of 10 g of wet muskeg with different concentrations of added mulch and hydroxyethylcellulose. Na2SiO3 is used as the precursor and the hydrolysis and condensation reaction is base catalyzed in each instance listed here.
