Publication number: 20240018046Abstract: The present invention provides exemplary method and additive for making cementitious binders that comprise primarily ground granulated blast furnace slag (GGBFS) having excellent strength at 24 hours, with preferably little or minimal amounts of Ordinary Portland Cement (OPC). As OPC manufacture involves carbon dioxide release into the atmosphere, the use of a GGBFS-based binder composition will help to enhance sustainability practices in the construction industry and minimizing strength losses implied by deletion of OPC. Strength in the GGBFS binder composition is enhanced by an alkaline-earth activator in combination with a strength enhancing component comprising dispersant and secondary activator.Type: ApplicationFiled: October 1, 2021Publication date: January 18, 2024Inventors: Pierre Estephane, Elizabeth Burns

Publication number: 20230032346Abstract: The present invention provides exemplary additive compositions and methods whereby hydratable cementitious compositions, such as concrete, can be modified using polycarboxylate type ether or ester cement dispersant polymers of a small size, in combination with at least one alkyl alkoxylate type surface active agent which typically hitherto is considered detergent-like in generating air bubbles (heads of foam) in aqueous environments. The present inventors discovered surprisingly that such agents could be used to control air content in plastic concrete mixes in combination with the polycarboxylate type ether or ester cement dispersant polymer.Type: ApplicationFiled: November 20, 2020Publication date: February 2, 2023Inventors: Elizabeth Burns, Hideo Koyata, Klaus-Alexander Rieder

Patent number: 11352301Abstract: The present invention relates to very high workable yet controllable concrete mix design, admixture composition, and process for placing concrete. The mix design relates to particular aggregate/cement ratios and types which are characteristic of ready mix concrete (RMC), which provide high fluidity reminiscent of self-consolidating concrete (SCC), and which provides advantages over both RMC and SCC in terms of ease and speed in placement and finishability at the construction site placement zone, regardless of whether into a horizontal formwork (e.g., for slabs, floors) or into vertical formwork (e.g., for blocks, walls, columns, etc.), without loss of control and without generating high risks of segregation even when small amounts of water are added at the size to facilitate finishing of the concrete surface.Type: GrantFiled: October 11, 2017Date of Patent: June 7, 2022Inventors: Elizabeth Burns, Nathan A. Tregger, Hideo Koyata, Lawrence L. Kuo, Klaus-Alexander Rieder, Mark F. Roberts, David Myers

Publication number: 20220127192Abstract: The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.Type: ApplicationFiled: January 5, 2022Publication date: April 28, 2022Inventors: Elise Berodier, Nathan A. Tregger, Josephine H. Cheung, David F. Myers, LI Zhang, Dorota Kazmierczak, Lawrence R. Roberts, Denise A. Silva, Richard Sibbick, Jeffrey Thomas, Mark F. Roberts, Riccardo Stoppa, Elizabeth Burns

Publication number: 20210355031Abstract: Described are compositions and methods for controlled strength development in a hydratable cementitious material, and more particularly to the use of polymerizable monomer components, which are initiated and activated by a redox pair which are mixed in controlled fashion, for enhancing non-hydration strength within the matrix of the plastic hydratable cementitious material before setting of the cementitious material begins. Exemplary applications include minimizing pressures on formwork for high fluid ready-mix applications, enhancing support and bonding properties for integrated concrete slab work and other sequential applications, or facilitating speedy 3D printing applications, among other unique possibilities.Type: ApplicationFiled: August 29, 2019Publication date: November 18, 2021Inventors: Byong-Wa Chung, Nathan A.

Patent number: 10851019Abstract: Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.Type: GrantFiled: April 30, 2019Date of Patent: December 1, 2020Inventors: David T. Geary, Elizabeth Burns, Nathan A. Tregger

Patent number: 10256861Abstract: A floatable cell phone case floats, with a cell phone or other electronic device housed therein, on a liquid through use of enclosed polygonal units that define a polygonal air volume. The polygonal units form a seal with the cell phone to create buoyancy. The cell phone case comprises case body having a rear wall and enclosed sidewalls having a flange. The rear wall and sidewalls define a device placement zone. The device placement zone is sized to house the cell phone. The flange retains the cell phone within the device placement zone. The phone case further comprises enclosed polygonal units spanning upwardly from an inner surface of the rear wall into the device placement zone. Each of the polygonal units define a polygonal air volume.Type: GrantFiled: January 15, 2018Date of Patent: April 9, 2019Inventor: Nicole Elizabeth Burns
