    Abstract: A bench top board scoring device (10) is provided, including a frame (14) having a first end (16) and an opposite second end (18), a work area (20) defined between the first and second ends (16, 18), each end (16, 18) having at least one leg (22) configured for contacting a substrate (12). A track (36) is connected to the frame (14) and extends between the first end (16, 18, 38) and the second end (16, 18, 38), a carriage (42) is slidably mounted to the track (36) for travel between the first end (16) and the second end (18), and an arm (50) has an upper surface (52), a pivot end (54) pivotally connected to the carriage (42), and an opposite knife mount end (56). A knife blade (78) is mounted to the knife mount end (56). Wherein the present device (10) is constructed and arranged so that as the carriage (42) is moved from the first end (16) to the second end (18), wallboard samples placed in the work area (20) and contacted by the knife blade (78) receive a constant scoring force.

    Abstract: Disclosed are a gypsum board, and related slurries and methods. The gypsum board comprises a gypsum layer disposed between two cover sheets. The gypsum layer comprises a crystalline matrix of set gypsum and expandable graphite. The expandable graphite exhibits volume expansion at high temperatures. Optionally, unexpanded vermiculite can also be included in the gypsum layer to provide an expansion component at even higher temperatures. Because of synergy between the expandable graphite and unexpanded vermiculite in accordance with some embodiments, less vermiculite can be included in the board than in conventional board that contained vermiculite. The board desirably can pass one or more fire-related tests, and is a fire-rated board in some embodiments.

    Abstract: A method in which a stream (5) of dry cementitious powder passes through a first conduit and aqueous medium stream (7) passes through a second conduit to feed a slurry mixer (2) to make cementitious slurry (31). The cementitious slurry (31) passes through a third conduit and a reinforcement fiber stream (34) passes through a fourth conduit to feed a fiber-slurry mixer (32) which mixes the slurry (31) and discrete fibers to make a stream of fiber-slurry mixture (36). An apparatus for performing the method is also disclosed.

    Abstract: Disclosed is a foamed cementitious composition which limits or eliminates aggregate, especially porous lightweight aggregate and uses a lower than usual water to cementitious composition weight ratio. The stable cementitious foam mixtures may be employed to make cement boards and other cement products. The foamed cementitious composition was made with additions of PVOH foaming stabilizer and surfactant foaming agents to make foam water or by entrain air into cementitious slurry mixtures. The cementitious mixtures have a limited amount or preferably no perlite and no lightweight aggregate. The resulting foamed mixture had foam bubbles with size in the range of 50 to 200 μm. After setting the foamed cementitious composition the resulting set board has air cells with size in the range of 50 to 200 μm.
