Method For Producing Enhanced Soil Stabilization Reactions Between Lime And Clay Soils Due To The Effect Of Silica Addition
View pageUS Patent:
53360222, Aug 9, 1994
Filed:
Sep 11, 1992
Appl. No.:
7/943940
Inventors:
J. T. McKennon - Dallas TX
Norman L. Hains - Arlington TX
David C. Hoffman - Ft. Worth TX
Norman L. Hains - Arlington TX
David C. Hoffman - Ft. Worth TX
Assignee:
Chemical Lime Company - Fort Worth TX
International Classification:
C09K 1700
US Classification:
405263
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.
Hot Mix Asphalt And Method Of Preparation Thereof
View pageUS Patent:
55120938, Apr 30, 1996
Filed:
Oct 26, 1994
Appl. No.:
8/329436
Inventors:
Fred R. Huege - Colleyville TX
Robin E. Graves - Henderson NV
Timothy L. Salter - Fort Worth TX
Patrick Shields - Scottsdale AZ

Assignee:
Chemical Lime Company - Fort Worth TX
International Classification:
C09D 400
US Classification:
10628403
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.
Method And Composition For Use In Recycling Metal Containing Furnace Dust
View pageUS Patent:
51867427, Feb 16, 1993
Filed:
Nov 27, 1991
Appl. No.:
7/799407
Inventors:
David C. Hoffman - Ft. Worth TX
Norman L. Hains - Arlington TX
Norman L. Hains - Arlington TX
Assignee:
Chemical Lime Company - Fort Worth TX
International Classification:
C21B 124
US Classification:
75773
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.
Method For Preventing The Adverse Effects Of Swell In Sulfate Bearing, Expansive Clay Soils
View pageUS Patent:
52288080, Jul 20, 1993
Filed:
Nov 27, 1991
Appl. No.:
7/800630
Inventors:
J. T. McKennon - Dallas TX
Norman L. Hains - Arlington TX
David C. Hoffman - Fort Worth TX
Norman L. Hains - Arlington TX
David C. Hoffman - Fort Worth TX
Assignee:
Chemical Lime Company - Fort Worth TX
International Classification:
C09K 1700
US Classification:
405263
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.

6/550501
Inventors:
Norman L. Hains - Houston TX
Assignee:
Chemlime Corporation - NJ
International Classification:
C01F 1102
US Classification:
423640
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.
