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 sensor measures slump and rheological characteristics of the concrete and is connected to a system that adjusts the slump by monitoring the sensor within the interior surface of a concrete mixer and controlling liquid additions. Data is analyzed by a computer processing unit to determine the slump and rheological characteristics of the concrete, liquid required to meet the slump requirements. The measurement done by the sensor is more accurate then the existing methods because it brings into consideration the effect of the helix inside the mixer on the movement of the concrete mixture inside the mixer. Furthermore, this method also allows the operation of the sensor in “real” life situations where the rotation speed of the mixer can't be maintained at a fixed value. The fact that the sensor rotates with the drum and that the concrete mixture is pushed to the bottom of the mixing drum guaranties that all the concrete is “sampled” by comparing results collected from each revolution of the mixing drum.

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 polycarboxylate polymer is formed from particularly small-sized, specifically selected monomer constituents: (A) polyoxyalkylene monomer represented by the structural formula (R1)(R3)C═C(R2)((CH2)m(CO)nO(CH2)o(AO)pR4) wherein (AO)p represents linear ethylene oxide groups and p is 5-23 and more preferably 5-15; (B) unsaturated carboxylic acid represented by (R5)(R7)C═C(R6)(C(O)OM) wherein M represents an alkali metal, the ratio of component A to component B being 20:80 to 50:50; and, optionally, (C) a hydrophilic monomer represented by (R8)(R9)C═C(R10)(CX) wherein R8, R9, and R10 each represent hydrogen or methyl group, and X represents C(O)NH2, C(O)NHR11, C(O)NR12R13, SO3H, C6H4SO3H, or C(O)NHC(CH3)2CH2SO3H, or mixture thereof, wherein R11, R12, and R13 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: An apparatus and method to measure and control the slump of concrete by monitoring sensor within the interior surface of a concrete mixer and a liquid flow meter. Data is analyzed by a computer processing unit to determine the slump of the concrete, liquid needed the quantity of concrete within the mixer, the amount of concrete poured, and the starting and ending time of the pour.

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: Disclosed are surface retarder composition and method for etching cementitious materials which achieve a desirable light “acid etch” look without using muriatic (hydrochloric) acid or sand blasting, removing the human health and environmental concerns. Formulations in accordance with embodiments disclosed herein are easier to remove from formwork or molds after demolding than conventional retarder paints. Surface retarders prevent the hydration of cement particles, which allows the uncured layer of paste next to the form to be removed such as by washing with water or other fluids, or by brushing, revealing aggregates. Also disclosed are molded cement and concrete materials or articles exhibiting such light etch.
