Abstract
A synthetic cover for bulk material piles and loads in transit may be formed from a mixture of liquid, binder, and fibers. These constituents may be mixed and applied to cover a waste pile. The cover will harden to minimize water infiltration, wind blown dust, odor and affinity to birds, flies and other insects. The liquid may include water; the binder may include portland cement, portland cement with flyash, cement kiln dust with or without bentonite, or stone dust. The fibers may comprise shredded paper or wood or plastic fibers.
Claims28
A bulk material cover comprising the following constituents:
- approximately thirty percent to sixty percent, by weight, liquid;
- approximately forty percent to seventy percent, by weight, mineral binder;
- up to approximately ten percent, by weight, fibers;
- and
- wherein a mixture of the constituents forms a thick viscid slurry for application in a uniform layer of approximately a quarter of an inch to form said bulk material cover.
A method of covering bulk material comprising:
- mixing fibers sufficient to prevent erosion with a liquid to form a pre-mixture;
- mixing a binder reagent with the pre-mixture to form a final mixture, wherein the final mixture forms a thick viscid slurry;
- and
- applying the final mixture to the bulk material in a uniform layer of approximately a quarter of an inch to form a hardened or interim cover.
A bulk material cover comprising the following constituents:
- up to approximately forty five percent, by weight, liquid;
- a plurality, by weight, of a binder;
- a minority portion of cellulose fibers and plastic fibers sufficient to prevent erosion;
- and
- wherein a mixture of the constituents forms a thick viscid slurry for spraying in a uniform layer of approximately a quarter of an inch to form said bulk material cover.
A method of covering a bulk material pile comprising:
- mixing cellulose fibers and plastic fibers sufficient to prevent erosion with a liquid to form a pre-mixture;
- and
- mixing a binder reagent with the pre-mixture to form a final mixture, wherein the final mixture forms a thick viscid slurry for spraying in a uniform layer of approximately a quarter of an inch to cover the bulk material pile.
A method of covering a bulk material pile comprising:
- mixing a binder, cellulose fibers and plastic fibers sufficient to prevent erosion, and liquid together to form a mixture of a thick viscid slurry for spraying in a uniform layer of approximately a quarter of an inch to form a daily interim cover;
- coating the bulk material pile with the mixture;
- and
- allowing the coating of the mixture to harden as a cover on the bulk material pile.
