20110017101 | Process for Producing a Granular Material - The present invention relates to a process for producing a granular material | 01-27-2011 |
20110023756 | BINDER FOR MINE TAILINGS, ALLUVIAL SAND AND THE LIKE - A binder for mine tailings, alluvial sand and other aggregate used as a backfill for an underground void comprises ferrous slag, cement kiln dust and/or lime kiln dust, and Portland cement and/or lime; the binder displays strength characteristics better than or comparable to those achieved with conventional binders based on Portland cement or Portland cement and slag. | 02-03-2011 |
20120132111 | Method for Production of Hydraulic Binder - A method for the production of an alkali activated hydraulic binder, with the binder comprising slag, natural aluminum silicates, and an alkali activator, and the binder being free of CaSO | 05-31-2012 |
20120137933 | HEAVY WEIGHT CONCRETE COMPOSITION USING SLAG BYPRODUCTS - Disclosed is a heavyweight concrete composition using slag byproducts, including: ground granulated blast furnace slag; slow-cooled electric-arc-furnace oxidizing slag or atomized steel slag used as a fine aggregate; a coarse aggregate; water; and a chemical admixture based on 100 parts by weight high-early-strength cement. Thus, the heavyweight concrete composition contains a large quantity of steel slag and blast-furnace slag that are byproducts in iron-making and steel-making processes, thereby remarkably reducing an amount of emission of carbon dioxide and maximizing the recycling of waste resources for preserving the natural environment. As a result, an eco-friendly heavyweight concrete product can be made. | 06-07-2012 |
20120234209 | HYDRAULIC BINDER COMPRISING A GROUND BLAST FURNACE SLAG - The present invention concerns a hydraulic binder comprising a ground blast furnace slag in an amount comprised between 30% and 95% by mass on the binder, Portland cement clinker in an amount equal to or greater than 5% by mass on the binder, and at least one sulphate as activator, characterised in that said slag has the following properties and composition by mass: grinding fineness greater than 4000 cm2/g Blaine glass content greater than 80% SiO | 09-20-2012 |
106715000 | Calcium sulfate specified (e.g., gypsum, anhydrite, plaster of Paris, etc.) | 6 |
20100294171 | CONCRETE WITH A LOW CLINKER CONTENT - A process for the preparation of a wet concrete composition, including a stage of mixing of: Portland clinker in the form of grains having a Dv97 from 10 to 30 μm or having a Blaine specific surface greater than or equal to 5300 cm | 11-25-2010 |
20110214591 | SULFATE RESISTANT GROUND GRANULATED BLAST FURNACE SLAG, SULFATE RESISTANT CEMENT, AND METHOD OF PRODUCTION OF SAME - In sulfate resistant cement obtained by mixing ground granulated blast furnace slag, Portland cement, and high-dissolution rate gypsum for raising the sulfate resistance, the high-dissolution rate gypsum differs in grain size and specific gravity from the Portland cement, so uniform mixture is not easy. To obtain sulfate resistant cement exhibiting homogeneous initial solidification, it is important to uniformly mix the blast furnace slag, Portland cement, and high-dissolution rate gypsum. | 09-08-2011 |
20120291673 | Light-Weight Composition and Mix for Masonry, Mortar and Stucco - An application for a pre-mixed mortar, stucco or masonry composition includes a approximately 75% sand and 25% of a light-weight cement mix comprising a cement (either Portland cement or Gypsum), ground granulated blast furnace slag, sodium tall oil, sodium stearate, sodium C14-16 Alpha Olefin, linear alkyl benzene; and silicon dioxide. | 11-22-2012 |
20130298805 | HYDRAULIC BINDER WITH LOW CLINKER CONTENT - A hydraulic binder includes, in parts by mass: (a) from 20 to 60 parts of Portland clinker; (b) from 20 to 40 parts of slag; and (c) from 0 to 60 parts of inorganic material other than the clinker and the slag; the sum of (a), (b) and (c) being equal to 100 parts; which binder further includes a slag activator including, relative to 100 parts of the sum of (a) and (b): from 1.4 to 6.55 parts of alkali metal salt, expressed as equivalent—Na | 11-14-2013 |
