    Abstract: The present invention provides a multi-layer barrier assembly or device for post-installation injection of a resin, grout, or other fluid. The barrier device comprises first and second layers defining an intermediate open-matrix layer, and at least one injection conduit member in parallel orientation with respect to the first and second layers and having openings for injecting fluid into the intermediate open-matrix layer. The injection conduit may be located between and in parallel orientation with respect to the first and second layers, along an edge of the first and/or second layers, along an outer face of the first layer (if the first layer is a woven or nonwoven fabric), or at any combination of these locations, to enable fluid to be conveyed into the intermediate open-matrix layer. The invention also provides for use of a gel activator within the barrier device cavity, such as pre-installed on open-matrix structure which used for separating the first and second layers of the barrier device, such that a highly flowable injection fluid can be introduced into the device, and its gelation or hardening will be initiated or accelerated by the presence of the gel activator. This will allow for low power grout pumps to be used and facilitate the sealing of fine cracks in the surrounding concrete.

    Abstract: 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.

    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: 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.

    Abstract: The present invention pertains to the discovery that short chain aliphatic fatty acids, such as potassium sorbate, can be used in liquid-additive grinding compositions in the amount of at least 10%, more preferably at least 20%, and most preferably at least 30%, to mill carbonate materials into smaller particle size. The carbonate material can optionally be combined with another inorganic material in the grinding operation, such as limestone, lime, dolomites, talc, titanium dioxide, alumina, and kaolin, ceramics, and cement clinker. The use of the particularly described grinding additive composition are food-grade or food-contact approved, and are believed by the present inventors to resist the humectant behavior of the resultant ground particles which could in herently otherwise decrease efficiency of the particulate grinding process.

    Abstract: The invention provides a method and system for detecting “sneak” additions of water or other fluid into the mixing drum of a concrete delivery vehicle having an automated rheology (e.g., slump) monitoring system. Sneak fluid additions are detected based on continuous rheology monitoring, even where valves and flow meters on the delivery vehicle are not used for the fluid addition. The invention is effective for monitoring additions by truck drivers who might add water from an undocumented water source (e.g., hose) along the delivery route or at the site, to hasten pouring, placement, and finishing at the time of delivery. Once sneak fluid addition is detected, the methods and system provide for reporting in the form of alerts, alarms, or other indications that sneak fluid addition has occurred, including monitor graphs or printouts confirming existence and/or extent of sneak fluid added into the vehicle mixing drum.
