Patent number: 6816791Abstract: 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: GrantFiled: October 15, 2002Date of Patent: November 9, 2004Assignee: 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

Patent number: 6773646Abstract: Exemplary mechanically-flattened fibers of the invention comprise generally elongate bodies having varied width or thickness dimensions and micro-diastrophic surface deformities. Preferred fibers are elongate synthetic polymer or multipolymer blend fibers for reinforcing matrix materials such as concrete, shotcrete, gypsum-containing materials, asphalt, plastic, rubber, and other matrix materials. Preferred methods for manufacturing such fibers comprise subjecting synthetic polymer fibers to compressive forces sufficient to achieve flattening and surface micro-diastrophism without substantially shredding and abrading the fibers. Further exemplary fibers and methods involve mechanically-flattening intertwined or braided fibers or fiber bundles, thereby providing fibers having physical impressions thereon of the intertwinement or braidingand, optionally though preferably of micro-diastrophic surface deformities.Type: GrantFiled: July 21, 2003Date of Patent: August 10, 2004Assignee: W. R. Grace & Co.-Conn.Inventors: Klaus-Alexander Rieder, Neal S. Berke, Stephen J. Fyler, Michael Macklin

Publication number: 20040031223Abstract: The invention provides a method for making a concrete floor slab using subgrade waterproofing in a manner that favors the use of water-based adhesives for affixing floor covering materials. The method comprises casting a hydratable cementitious composition onto a flooring membrane, the composition having a shrinkage reduction admixture and a water:cementitious binder ratio sufficiently low that substantially all of the water moisture is retained in the hydration reaction, and achieving a fully adhered bond with the flooring membrane.Type: ApplicationFiled: August 15, 2002Publication date: February 19, 2004Inventors: Timothy A. Durning, Lawrence R. Roberts, Neal S. Berke

Patent number: 6648962Abstract: Substantially hydrated cementitious particulates useful for delivering admixtures and additives into adhesives, coatings, paints, and other matrix compositions such as cement, concrete, masonry, mortar, fireproofing, shotcrete, and others. Preferred embodiments include intermixing at least one admixture, water, and hydratable cementitious binder to provide a substantially hydrated hardened mass and comminuting the hardened mass into particulates. Alternatively, or in addition, one or more admixtures may be coated onto the external surface area of the particulates, which are microscopically granulosic, to provide accurate and high level loading.Type: GrantFiled: September 6, 2001Date of Patent: November 18, 2003Assignee: W.
