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: 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.
