Patent number: 7141112Abstract: Cementitious materials including stainless steel slag and geopolymer can be added to conventional cement compositions, such as Portland cement, as a partial or total replacement for conventional cement materials. The stainless steel slag may comprise silicates and/or oxides of calcium, silicon, magnesium, iron, aluminum, manganese, titanium, sulfur, chromium and/or nickel. The geopolymer may comprise aluminum silicate and/or magnesium silicate. In a preferred embodiment, curing of concrete materials by the action of water on the cementitious materials is enhanced with the addition of an activator component selected from calcium bromide, calcium nitrate, calcium nitrite, calcium chloride, calcium oxide, and sodium bromide.Type: GrantFiled: March 21, 2005Date of Patent: November 28, 2006Inventor: Douglas C Comrie

Patent number: 7138012Abstract: Use of waste generated as a byproduct of a first manufacturing process as an air entraining admixture (AEA) in a second product. In some instances, the waste materials can be used as an AEA during cement and/or concrete formation, and may also be waste materials produced during shampoo manufacturing. It is contemplated that the use of non-conventional materials as an AEA conventional applications will often result in products that have performance characteristics similar to conventional AEAs.Type: GrantFiled: September 9, 2002Date of Patent: November 21, 2006Assignee: Waste Markets CorporationInventors: David Long, M. D. Poole

Patent number: 7118624Abstract: The present invention provides a novel method to produce grade road base material using recycled oilfield waste, called “oil and gas waste,” more specifically, drilling waste and aggregate and a novel road base material. Hydration and mixing of the waste materials along with a binder, will achieve an irreversible pozzolanic chemical reaction necessary for stabilization into a road base. An asphalt emulsifier may be included in the binder to manufacture asphalt stabilized road base. The entire method is a cold batch process.Type: GrantFiled: March 16, 2004Date of Patent: October 10, 2006Inventor: David L. Polston

Patent number: 7037368Abstract: A method for the production of cement clinker comprises the introduction of non-traditional materials into the kiln, preferably at a mid-kiln locations. The non-traditional materials are materials that are difficult, expensive or environmentally challenging for disposal. In one embodiment, weathered clinker is introduced into the kiln to admix with the raw material mix to augment clinker production. In another embodiment, bird, animal or human manure is added to the kiln so that gaseous reducing agents can be released by the manure and combine with certain noxious gases generated during the clinker production, to thereby reduce the noxious gas output. In other embodiments, other non-traditional waste-derived fuels are added to the kiln during clinker production, including railroad ties coated with creosote, industrial, commercial and consumer rubber components, such as rubber hoses, unshredded plastics, and organic materials, such as bird and animal meal.Type: GrantFiled: April 29, 2004Date of Patent: May 2, 2006Assignee: Buzzi Unicem USA, Inc.Inventor: Lawrence L. Hoffis

Patent number: 6890507Abstract: Carbon-containing fly ash has been treated with optimum amounts of ozone. There is homogenous treatment of the fly ash with ozone and over saturation with ozone is avoided. In a further embodiment of the invention carbon, from various sources is oxygenated to be incorporated into concrete. The preferred oxygenating agent is ozone.Type: GrantFiled: September 17, 2002Date of Patent: May 10, 2005Assignee: Brown University Research FoundationInventors: Xu Chen, Yuming Gao, Robert H. Hurt, Eric M. Suuberg, Arun K. Mehta

Patent number: 6869475Abstract: An asbestos free, calcium silicate insulating material, suitable for use in applications where a tough, fire resistant, heat insulating, electrical insulating, and corrosion resistant material is desirable. The calcium silicate insulating material is produced by combining Portland cement, blast furnace slag cement, a siliceous component, wollastonite and organic fibrous material in the presence of water to form a slurry. The slurry is then placed under steam pressure, to react the portland cement, blast furnace slag cement, siliceous component and water, dried, and heat treated if necessary.Type: GrantFiled: October 28, 2003Date of Patent: March 22, 2005Assignee: BNZ Materials, Inc.Inventor: Thomas R.
