Method of soil stabilization using fibers

摘要

A soil stabilization mixture comprising a mixture of soil to be stabilized, fibers and binder. The soil and the fibers are mixed together. The binder, which acts as a chemical stabilizer, is then added and mixing continues. The mixture is then applied to the soil to be stabilized and the stabilized soil is then compacted. The fibers can be recycled carpet fibers, fiber reinforced polymer, biofibers or a mixture thereof. The binder includes mixtures of Portland cement and at least one of crushed glass, metakaolin and ground blast furnace slag.

1. A method of stabilizing a quantity of soil comprising:
mixing a quantity of soil with 0.5-3.0% (w/w) fibers to a substantially homogeneous mixture, said fibers being selected from the group consisting of: recycled carpet fibers; fiber reinforced polymer; biofibers and mixtures thereof; adding to said mixture 5-40% (w/w) of a binder, said binder comprising a mixture of Portland cement, and one or more of ground blast furnace slag, crushed glass and metakaolin, said mixture comprising 50-85% (w/w) Portland Cement; 0-50% (w/w) crushed glass; 0-15% (w/w) metakaolin; and 0-50% (w/w) ground blast furnace slag; and compacting the mixture.
