    Abstract: 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.

    Abstract: Described are a method and system for coordinating the delivery and placement of concrete loads at a job site, and more particularly to adjusting a set time value or value range of the concrete loads, thereby to facilitate finishing or other concrete placement activities. In exemplary embodiments, the adjustments can be made based on an assessment of previously placed concrete loads. The set time values or value ranges of the concrete can be monitored and adjusted to achieve desired properties during installation and/or in its hardened state.

    Abstract: 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. An inventive admixture combination which enables this unique design involves two different polycarboxylate comb polymers in combination with two specific viscosity modifying agents, and this combination provides highly workable concrete to be placed in a controlled, efficient manner.

    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 present invention provides a multi-layer barrier assembly or device for post-installation injection of a resin, grout, or other fluid 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: 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.
