Abstract
The present invention provides semi-solid and reinforced soil mixtures formed from aqueous soil mixtures such as dredge material, discrete reinforcing fibers such as glass fibers. The reinforced mixtures can include additives for partially solidifying the aqueous soil mixture, such as calcium-containing materials, cementitious materials, silicon-containing materials, aluminum-containing materials and mixtures thereof. The pH of the reinforced soil mixture can be adjusted to control deterioration of the reinforcing fibers, as desired.
