| 20110048286 | CEMENTITIOUS COMPOSITIONS CONTAINING FELDSPAR AND POZZOLANIC PARTICULATE MATERIAL, AND METHOD OF MAKING SAID COMPOSITION - A method of making a cementitious composition comprises (a) selecting at least one pozzolanic particulate material; (b) selecting and grinding at least one feldspar material to a fineness of at least 3000 Blaine; (c) mixing calcium oxide or calcium hydroxide with gypsum; (d) mixing the ground feldspar with the lime-gypsum mixture to produce an activator; (e) conditioning the pozzolanic particulate material with an aqueous solution; (f) adding the activator to the conditioned material to produce a slurry; and (g) curing the slurry in a sealed container. The pozzolanic particulate material can be slag, fly ash, or siliceous rock. A cementitious composition of the invention comprises a pozzolanic particulate material, a ground feldspar material, a lime compound and gypsum, and uses readily available materials, as an economic replacement for Portland cement, fly ash or other materials in filling, backfilling and paving, particularly for backfilling or stabilizing mine sites. | 03-03-2011 |
| 20120318174 | Sealant Compositions and Methods of Use - A sealant composition may include a fly ash, hydrated lime, and at least one filler material selected from the group consisting of sand, barite, calcium carbonate, ground marble, iron oxide, manganese oxide, glass beads, crushed glass, crushed drill cuttings, ground vehicle tire, crushed rock, ground asphalt, crushed concrete, crushed cement, salt, ilmenite, hematite, silica flour, diatomaceous earth, a highly swellable clay miner, and any derivative thereof, and wherein the fly ash and hydrated lime together are present in an amount from about 0.25% to about 30% by weight of the sealant composition. | 12-20-2012 |
| 20130213275 | METHOD OF FORMING STRUCTURE UTILIZING A HYDRATED LIME MATERIAL - A method of forming structures utilizing a hydrated lime material. A hydrated lime material is formed that is impermeable to water that is formed by subjecting a quicklime to a mixer and adding a surfactant and water to form the hydrated lime. The hydrated lime is then blended with a composite material to form a blended material that is impermeable to water. This blended material is then utilized in differing structures in order to form structures that are impermeable to water. | 08-22-2013 |
| 20130305963 | Method of producing activated construction mixture - In a method of producing an activated construction mixture including cement, water, additives and superplasticizer the activation is performed with dimensionless criteria Reynolds and Power numbers within the limits of 20-800 and 4.0-0.1 respectively for increasing water adsorption with calcium silicate hydrate colloid formation and accelerating cement hydration. | 11-21-2013 |
