    Abstract: Disclosed is a method for determining volume of a concrete mix load in a mixer drum based on use of an in-and-out sensor probe which submerges into and exits from the concrete during drum rotation and which provides data to a processor used for calculating volume based on the data. To provide for concavity, convexity, and/or cascading surface flow effects that can hinder accurate determination of the concrete load volume, the processor may be configured to compare original batch volume and/or rheology of the concrete load monitored during drum rotation. The calibration of load volume value, highly useful for monitoring or admixture dosing purposes, can be done based on comparison of real-time data with historic data gathered over time and stored in processor-accessible memory. Further exemplary embodiments also take into account the speed and/or tilt of the drum (due to roadway conditions), concrete mix design, and other factors.

    Abstract: Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.

    Abstract: The present invention provides methods and articles for achieving puncture- resistant waterproofing membranes and for waterproofing building and civil engineering surfaces without requiring the use of separate protection boards. Exemplary membranes and methods of the invention rely on relatively thin, flexible composite layers to provide impact resistance while yet facilitating seaming between adjacent installed membranes and minimizing formation of wrinkles, leakage channels, and "fish mouth" openings, particularly at substrate details or other surface irregularities.

    Abstract: 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.

    Abstract: The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within 1/8 inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.

    Abstract: 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. Yet, the present inventors achieved an additive in the form of a stable liquid suspension which can be conveniently dosed into concretes and shotcrete mixtures, to enhance early age strength, and to improve workability and rheology in terms of finishability of concrete surfaces and improved rebound performance in shotcrete applications.
