Abstract: A method and apparatus for providing an evenly mixed additive enhanced gypsum slurry to a web. Calcined gypsum and water are inserted into a mixer (12) through at least one inlet (26,28) of the mixer (12). The contents are agitated to form a slurry. The slurry is passed from an outlet (34) of the mixer (12) into a conduit (38). An additive is introduced into the slurry along a length of the conduit (38) to achieve a flow stream of a slurry/additive mixture. A cross section (60) of the flow stream is expanded in the conduit (38) while not changing direction of the flow stream and a direction of the flow stream is changed while not expanding the cross section (60) of the flow stream and conduit (38), all prior to the flow steam exiting from an outlet (42) of the conduit.

Abstract: Embodiments of a system (50) and a method for manufacturing a cementitious panel (10) can be used to produce a cementitious panel (10) having a multi-layer air/water barrier membrane assembly (18). The layers (21, 22, 23) of the membrane (18) can be built up via a series of applicator stations (72, 75, 78) applying a fluid composition using roll coating, for example. Between applicator stations (72, 75, 78) the applied layer of fluid composition can be subjected to drying conditions via infrared heating. To help protect from the deleterious effects of infrared heating, the cementitious panel (10) can be conveyed through a cooling tunnel (93, 103, 113) after each drying section (92, 102, 112).

Abstract: A slurry distributor can include a distribution conduit and a slurry wiping mechanism. The distribution conduit extends generally along a longitudinal axis and includes an entry portion, a distribution outlet in fluid communication with the entry portion, and a bottom surface extending between the entry portion and the distribution outlet. The distribution outlet extends a predetermined distance along a transverse axis, which is substantially perpendicular to the longitudinal axis. The slurry wiping mechanism includes a movable wiper blade in contacting relationship with the bottom surface of the distribution conduit. The wiper blade is reciprocally movable between a first position and a second position over a clearing path, which is disposed adjacent the distribution outlet.

Abstract: Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention have many uses, such as, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.
