Abstract
A method and formulation are shown for capping dust-emitting bulk materials, such as materials being conveyed in open rail cars. A mineral formulation is prepared by mixing together lime, a pozzolanic component, a sulfate component, a fibrous component and water. The mineral formulation is applied to the surface of the dust-emitting bulk material and is allowed to harden to form a surface coating thereon.
Claims10
A method of capping a particulate material being transported within a container having at least one opening therein which provides an exposed surface of the particulate material which tends to become airborne due to the influence of environmental factors including wind and vibration, the method comprising the steps of:
- preparing an initially liquid slurry by mixing together lime, a pozzolanic component, a sulfur containing component, a fibrous component and water;
- applying the initially liquid slurry to the exposed surface of the particulate material while the particulate material is located within the transport container;
- and
- allowing the initially liquid slurry to harden to a solid mass which substantially covers the exposed surface to be capped.
A method of capping a rail car containing a particulate material having an exposed surface which tends to become airborne due to the influence of environmental factors, the method comprising the steps of:
- preparing an initially liquid slurry at a first location by mixing together lime, a pozzolanic component, a sulfur containing component, a fibrous component and water;
- applying the initially liquid slurry to the exposed surface of the particulate material contained within the rail car;
- and
- allowing the initially liquid slurry to harden to a solid mass which substantially covers the exposed surface to be capped prior to transporting the particulate material to a second location.
A method of capping particulate material having an exposed surface which tends to become airborne due to the influence of environmental factors, the method comprising the steps of:
- preparing an initially liquid slurry by mixing together lime, a pozzolanic component, a sulfur containing component, a fibrous component and water;
- applying the initially liquid slurry to the exposed surface of the particulate material to be capped;
- and
- allowing the initially liquid slurry to harden to a solid mass which substantially covers the exposed surface to be capped, the solid mass having an unconfined compressive strength which is greater than about 600 psi.
