Abstract: The present invention discloses cementitious compositions which contain hydratable cement, limestone, or mixture thereof, having improved strength properties due to the presence of calcined clay and certain higher alkanolamines, wherein the calcined clay has an Fe2O3 content of greater than one percent (1%). Also disclosed are exemplary additives and methods for enhancing strength of cement and/or limestone compositions.

Abstract: The present invention provides compositions and methods involving the use of a carboxylate graft polymer having high molecular weight and low ratio of acid-to-polyoxyalkylene groups. Such clay-mitigation is particularly useful for treating clay and clay-bearing aggregates, particularly those aggregates used for construction purposes. The present invention minimizes the need to wash the aggregates, thus preserving fine aggregates (“fines”) content in construction materials, and thereby beneficiating the performance and/or properties of construction materials containing the clay-bearing aggregates.

Abstract: A method of fabricating a concrete slab system places bed of a first concrete on a base. The bed has a top surface, a bottom surface, and edge surfaces. The bed is exposed to a drying environment such that the top surface develops shrinkage cracks and portions of the bed separate from the base. A force applied to the top surface induces non-shrinkage cracks in the bed that extend to the bed's bottom surface. Non-concrete material is placed on the bed's top surface and on each of its edge surfaces. The non-concrete material and bed are covered with a second concrete having stretchable fibers mixed therein.

Abstract: Methods for plasticizing cementitious mixtures having relatively high water/cement ratio (at least 0.40 or higher) are surprisingly improved in terms of dosage efficiency, compared to conventional “superplasticizer” polycarboxylate polymers, when the comb-type carboxylate copolymer is formed from two different polyether side chains, specifically selected monomer constituents: (A) first polyoxyalkylene monomer represented by structural formula (R1)(R3)C═C(R2)((CH2)m(CO)nO(CH2)o(AO)pR4) wherein (AO)p represents linear alkylene oxide and p is an integer of 5-23; (B) second polyoxyalkylene monomer represented by structural formula (R1)(R3)C═C(R2)((CH2)m(CO)nO(CH2)o(AO)qR4) wherein (AO)q represents linear alkylene oxide groups and q is an integer of 20 to 200; (C) unsaturated carboxylic acid monomer represented by (R5)(R7)C═C(R6)(C(O)OM) wherein M represents an alkali metal, and the ratio of component A to component B is 20:80 to 50:50; and, optionally, (D) a water-soluble monomer represented by (R8)(R9)C═C(R10)(X) wherein R8, R9, and R10 each represent hydrogen or methyl group, and X represents C(O)NH2, C(O)NHR11, C(O)NR12R13, OR14, SO3H, C6H4SO3H, or C(O)NHC(CH3)2CH2SO3H, or mixture thereof, wherein R11, R12, R13, and R14 each represent a C1 to C5 alkyl group.

Abstract: The present invention provides a fast response method and system wherein one or more comb-type polycarboxylate ether (PCE) polymers, having a cumulative absorptivity coefficient in the range of 40%-75%, are employed as fluidizing admixtures dosed into concrete by and in automated slump monitoring and control systems which iteratively monitors and adjusts the slump of the concrete mix.

Abstract: Methods and systems of the invention, for achieving a liquid-applicable, aqueous-based coating composition that forms a water-impermeable, vapor permeable barrier coating when applied onto a construction surface and allowed to dry, involve mixing together separate first and second components, wherein the first component comprises an acrylic emulsion, flame retardant, clay, and optionally at least one additive selected from thickeners (e.g., cellulosic), fillers, and other conventional additives; and wherein the second component comprises a freezing point depressing agent with a specific type of thickener selected from the group of associative thickeners, alkali soluble emulsion thickeners, or mixture thereof, to obtain the liquid-applicable coating. The present invention achieves low temperature film formation without reliance upon calcium nitrite, calcium nitrate, or sodium chloride type of freezing point depressing salts. The coating can be applied at low (e.g., sub-freezing) temperatures onto a construction surface such as wood, fiberboard, gypsum, cement, concrete, and other building substrates to achieve an effective barrier membrane.

Abstract: System and method of the invention involves use of a sensor-containing body which is mounted and/or rotatably disposed along the longitudinal rotational axis of a concrete mixer drum at the close end, the sensor-containing body being connected to a conduit for introducing water, chemical admixture, gas, and/or cleansing fluid through the closed end of the drum into the mixer drum. Numerous heretofore unrealized combinations of advantages and benefits are provided within the concrete industry by the invention.

Abstract: 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.

Abstract: 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.

Abstract: A composition and method for stabilizing or consolidating low permeability soil, rock, coal, mineral, or other loose aggregates, especially in a subterranean environment. Disclosed is a two-component, acrylate-based injection resin that includes a first component and a second component. The first component comprises an acrylate and an accelerator, and the second component comprises a radical initiator. At the application site, the components are mixed together to form a liquid resin mixture with sufficiently low viscosity, such that the mixture can permeate the low permeability soil. The mixture is injected into the soil in need of stabilization and undergoes polymerization and curing, in turn forming a subterranean geocomposite having high compressive strength.
