Patent number: 11958774Abstract: Method and composition for producing aggregates from cement and concrete, including residual or returned concrete. Exemplary methods involve the use of an aggregate-forming inducer that provides a surface anchoring site for cement paste to bond/adhere, such as shredded news print, cardboard, or mixtures thereof, and also including fiber materials such as polymers, glass, and other material fibers. The aggregate-forming inducer is mixed with fresh concrete until aggregates are formed.Type: GrantFiled: May 11, 2018Date of Patent: April 16, 2024Assignee: GCP APPLIED TECHNOLOGIES INC.Inventors: Antonio J. Aldykiewicz, Jr., Klaus-Alexander Rieder, Michael D. Morgan, Djassi-biko Rodrigues Pires

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: 11390561Abstract: The present invention provides a liquid composition of quicklime particles within an alkylene glycol-based paste or slurry environment, which allows for pumpability and meterability of a liquid composition into cementitious materials such as concrete and mortar. Treated quicklime particles of the present invention manifest an unexpected and surprising hydration induction postponement behavior, as demonstrated through calorimetric testing.Type: GrantFiled: October 13, 2017Date of Patent: July 19, 2022Assignee: GCP Applied Technologies Inc.Inventors: Zen Chun, Klaus-Alexander Rieder, Ezgi Yurdakul, Antonio J.

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: 20210188709Abstract: A method for manufacturing a concrete article is disclosed. The method comprises coating a mould or formwork with a release agent; spraying a mortar onto the mould or formwork, thereby forming a layer of mortar; casting concrete into the mould or formwork and onto the layer of mortar; and allowing the concrete to hydrate and harden in the mould or formwork, whereby a concrete article having a mortar skin layer is provided. The invention also provides concrete articles made by the described methods, and concrete structures which comprise the concrete articles. Concrete articles having the mortar skins can be made to have a relatively uniform outward appearance, even if the concrete cast behind the mortar skins may be different, in composition or appearance. Pigments or colorants and other expensive admixtures can be used in the mortar skin composition to greater visual effect, since the use of the mortar skin is less in overall volume compared to the concrete articles as a whole.Type: ApplicationFiled: June 12, 2018Publication date: June 24, 2021Inventors: Dany Vincent, Klaus-Alexander Rieder, Stephen P. Klaus, Damian Thomas

Patent number: 10577284Abstract: The present invention provides an admixture composition comprising a liquid suspension of colloidal silica, siloxane, and polycarboxylate polymer cement dispersant for enhancing early age strength, finishability, and other properties in hydratable cementitious compositions such as concrete (e.g., shotcrete). An inventive method involves mixing the components together in a specific sequence, thereby to obtain a stable liquid suspension. This attainment of a stable liquid suspension is surprising and unexpected because (i) the polycarboxylate polymer cement dispersant and siloxane components are incompatible and immiscible with one another; and (ii) that colloidal silica and siloxane compound are incompatible and immiscible with one another.Type: GrantFiled: June 27, 2018Date of Patent: March 3, 2020Assignee: GCP Applied Technologies Inc.Inventors: Ezgi Yurdakul, Damla Boyer, Klaus-Alexander Rieder, Yohannes K.

Patent number: 9624130Abstract: The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.Type: GrantFiled: February 5, 2016Date of Patent: April 18, 2017Assignee: GCP Applied Technologies Inc.Inventors: Lawrence L. Kuo, Keith St Jean, Yohannes K. Lemma, Nathan A. Tregger, Stephen P. Klaus, Danila F. Ferraz, Klaus-Alexander Rieder, Pierre Estephane
