Patent number: 9394200Abstract: Pozzolanic cement compositions and method manufacturing the same are described. These cement compositions may include a pozzolanic material and an activator based on a salt of glycolic acid, glyceric acid, malic acid, tartaric acid, malonic acid, glutaric acid, maleic acid, formic acid, acetic acid, propionic acid, or butyric acid, a retarder based on hepto-gluconates, sulfate salts, sugars, sugar acids, lignins, and/or an accelerator based on amines. The cement compositions may have less than 10% by weight Portland cement. The pozzolanic cement compositions including these activators, accelerators, and retarders can have improved properties such as longer setting time, better slump retention, and improved strength.Type: GrantFiled: November 1, 2013Date of Patent: July 19, 2016Assignee: Ceratech IncInventors: Ivan Diaz-Loya, Rajeshkumar Patel, David Hoffman, Joseph Trzpekowski, Frederick Kinney

Patent number: 8747548Abstract: Cementitious compositions in which the cementitious properties of fly ash are carefully controlled are described. The cementitious compositions may be substantially free harsh acids and bases such as citric acids (?pH 2.2) and alkali metal activators including alkali hydroxides (?pH 12-14) and metal carbonates (?pH 11.6). The use of these harsh chemicals creates acid base reactions during use of the products. Instead of these harsh chemicals, a lactic acid salt based activator is be used as a reaction accelerator. Boric compounds may be used as a retarder in the compositions.Type: GrantFiled: January 4, 2013Date of Patent: June 10, 2014Assignee: Ceratech Inc.Inventors: Glenn Schumacher, Rajeshkumar Patel

Patent number: 8186106Abstract: Cementitious compositions in which the cementitious properties of fly-ash are carefully controlled. The cementitious compositions may be substantially free harsh acids and bases such as citric acids (?pH 2.2) and alkali metal activators including alkali hydroxides (?pH 12-14) and metal carbonates (?pH 11.6). The use of these harsh chemicals creates acid base reactions during use of the products. Instead of these harsh chemicals, a citric salt, for example potassium citrate, may be used as a reaction accelerator. Boric compounds may be used as a retarder in the compositions.Type: GrantFiled: August 3, 2011Date of Patent: May 29, 2012Assignee: CeraTech, Inc.Inventors: Glenn Schumacher, Rajeshkumar Patel, Paul Sampson, Michael Riley
