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: 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: Method and composition for producing aggregates from cement and concrete, including residual or returned concrete. Exemplary methods involve the use of an aggregate-forming inducer that provides a surface anchoring site for cement paste to bond/adhere, such as shredded news print, cardboard, or mixtures thereof, and also including fiber materials such as polymers, glass, and other material fibers. The aggregate-forming inducer is mixed with fresh concrete until aggregates are formed.

Abstract: Described are compositions and methods for controlled strength development in a hydratable cementitious material, and more particularly to the use of polymerizable monomer components, which are initiated and activated by a redox pair which are mixed in controlled fashion, for enhancing non-hydration strength within the matrix of the plastic hydratable cementitious material before setting of the cementitious material begins. Exemplary applications include minimizing pressures on formwork for high fluid ready-mix applications, enhancing support and bonding properties for integrated concrete slab work and other sequential applications, or facilitating speedy 3D printing applications, among other unique possibilities.

Abstract: An integrated air barrier assembly is provided as an integral product in which a fastener-sealing layer is secured between opposed surfaces of a board and an anti-blocking facing layer. The assembly exhibits good fastener sealability, including for larger self-drilling screws. The anti-blocking facing layer maintains the fastener-sealing layer inward of the environment and prevents blocking or sticking of the assembly when stacked. In some embodiments, the anti-blocking facing layer can be a metal film or foil, which can reflect heat away from the fastener-sealing layer, thereby maintaining a lower temperature on the fastener-sealing layer. In some embodiments, the board can be an insulating layer or wood layer. The assembly can be readily installed in a single step during construction.

Abstract: A method of making a cement composition, comprising grinding a cement clinker and a strength-enhancing agent, thereby producing a hydraulic cementitious powder, wherein the strength-enhancing agent is present in the hydraulic cementitious powder in an amount of from 0.001% to 0.09% based on dry weight of the hydraulic cementitious powder. The strength-enhancing agent is a compound represented by the following structural formula (I). The definitions of variables R1, R2, and R3 as well as R10, R20, and R30 are provided herein.

Abstract: The present invention provides a method and admixture composition for making hydratable cementitious compositions, ones believed to have much less stickiness in comparison to prior methods. Decreased stickiness in concrete mixes means that they are easier to pour or to cast into place, as well as easier to finish. Dispersant carboxylate polymers of the invention having this ability are characterized by possessing two different, relatively short chain lengths of polyalkyleneoxide units and low weight-average molecular weights.
