  • Assay methods for hydratable cementitious compositions
    Patent number: 6816791
    Abstract: A novel methodology for rapid, cost-efficient discovery, identification, or improvement of additives and/or admixtures for hydratable cementitious compositions. Multiple formulations comprising hydratable cementitious compositions are deposited into a plurality of receptacles. A first assay output is obtained, such as through x-ray diffraction, which is then correlated to provide a second assay output value corresponding to physical or chemical properties of the cementitious compositions.
    Type: Grant
    Filed: October 15, 2002
    Date of Patent: November 9, 2004
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: David F. Myers, Felek Jachimowicz, Joanna D. Blanchard, Neal S. Berke, Josephine H. Cheung, Paul J. Sandberg, Frank G. Serafin, Peter V. Coveney

Multiple formulations comprising hydratable cementitious compositions are deposited into a plurality of receptacles. A first assay output is obtained, such as through Raman spectroscopy, which is then correlated to provide a second assay output value corresponding to physical or chemical properties of the cementitious compositions.

  • Method of grinding a hydraulic cement
    Patent number: 4711401
    Abstract: Hydraulic cements such as Portland cement are interground with diesters formed by reacting a polyol (e.g. alkylene glycol) with a monobasic carboxylic acid (e.g. acetic acid) to enhance the efficiency of the grinding operation.

  • Gypsum-free cement compositions
    Patent number: 4405372
    Abstract: Disclosed herein are gypsum-free cement compositions comprising portland cement, limestone and an amine salt of formic or acetic acid. The compositions exhibit compressive strength comparable to ordinary portland cement compositions containing gypsum and the setting properties of the compositions can be regulated.
