Abstract: A limestone based masonry veneer composition is described that may be molded, blown, sprayed, troweled, or otherwise applied to interior and exterior surfaces. The composition provides an aesthetic resurfacing, cladding and/or overlay coating. The composition is capable of being pigmented, textured, sculpted—or otherwise formed into an aesthetic, realistic, architecture, suitable as a stone veneer, an example of which is Blown Stone®, by Stone Coat®. Texturing or sculpting may occur about 1 hour and up to about 12 hours after applying the composition. The final composition is hydrophobic and breathes. Air carbonation allows the formation of a predominantly very pure calcium carbonate or limestone when fully cured, which prevents mold and algae growth and allows for autogenous healing with an increase in unit weight over time, ensuring an overall high compressive strength that endures over time.

Abstract: A method is shown for improving the properties of hot mix asphalt by treating the aggregate which is combined with bituminous binder with lime. A hot quicklime slurry is produced by slaking quicklime with water at the site of the hot mix asphalt plant using a portable mixing tank. The hot quicklime slurry is then applied to the aggregate, the aggregate is dried and combined with the binder to produce the hot mix asphalt.

Abstract: A method is shown for stabilizing clay bearing soils in which a silica compound is incorporated into the soils in addition to the application of lime. The silica compound can be either an amorphous, silica fume, a crystalline silica, a silica gel, sodium silicate, potassium silicate, finely ground glass or combinations thereof. The silica compound promotes the formation of calcium silicate hydrates over the formation of calcium aluminate hydrates in the resulting pozzolanic reaction occurring in the clay bearing soils. The silica compound and lime can be incorporated into the soils in a single step.

Abstract: A method is shown for stabilizing sulfate bearing soils in which a silica compound is incorporated into the soils with the soils being further stabilized by the application of lime. The silica compound can be either an amorphous, flume silica, a crystalline silica, a silica gel, sodium silicate, potassium silicate or combination thereof. The silica compound and lime can be incorporated into the soils in a single step.

Abstract: A process is shown where an arc dust waste produced by an electric arc furnace is conducted to silos and converted to a reusable co-product by means of the addition of a special blend of high calcium and dolomitic quicklime, calcium stearate and pulverized waste paper. The mixture is compressed into compact pellets which, due to their impact integrity and improved shelf life can be pneumatically conveyed intact into storage silos for recycling of the waste electric arc flue dust into the furnace melt. Components of the arc dust deemed leachable and hazardous in landfills, such as zinc, lead and chromium are increased in concentration to a point where it is economical to extract them for resale.

Abstract: A method for forming a lime slurry in which a sulfate compound is mixed with an aqueous slaking medium and in which the resulting sulfate/water mixture is admixed with calcium oxide.
