Abstract: Embodiments of a system and a method for evaluating a joint compound specimen can be used to determine a numerical sandability value for the specimen. A moving assembly is configured to move a sanding member in a sanding direction relative to the joint compound specimen supported in a support fixture. An actuator assembly is configured to drive the sanding member into contacting relationship with the joint compound specimen such that the sanding member exerts a controlled amount of pressure against the joint compound specimen. The force gauge is configured to measure a resistance force against the sanding member in a resistance direction in opposing relationship to the sanding direction. A processor programmed with a joint compound analyzing application is configured to use a force signal from the force gauge that is indicative of the resistance force to determine the sandability value for the joint compound specimen.

Abstract: Method of making foamed gypsum slurry having 15 to 90 volume percent gas bubbles including: passing first slurry including water and on dry basis 50 to 98 wt. % calcium sulfate hemihydrate, 1 to 50 wt. % calcium carbonate, and 0.1 to 10 wt. % cellulose thickener via a first hose to a Wye connector conduit first inlet opening at Rate C and passing alum solution via a second hose to a second inlet opening of the conduit at Rate D to create combined mixed stream passing from the conduit to a static mixer for mixing for Time 3 to activate at least a portion of the calcium carbonate and alum to generate CO2 and create the foamed gypsum slurry; transferring the slurry from the mixer to a cavity between two wall boards via a third hose. Allowing the slurry in the cavity to expand, harden and dry.

Abstract: An interior wall is provided, including a frame including at least one footer, at least one header, at least one vertical frame member connecting at least one of the at least one footer to at least one of the at least one header, the frame having a first side and a second side, and defining an interior frame space. A first wallboard panel is fastened to the first side of the frame. At least one gypsum wallboard stud is secured in the interior frame space, being fastened to the first wallboard panel and being dimensioned to extend from the first side to the second side. A second wallboard panel is fastened to the second side of the frame and to the at least one gypsum wallboard stud for creating a continuous acoustic connection between the first wallboard panel and the second wallboard panel.

Abstract: A joint tape embedding apparatus configured to determine the bonding and/or “feel” of embedding joint tape into a dry wall or wall board joint using a particular joint compound. The joint embedding apparatus is configured to allow the same user or different users to accurately repeat the determination of the bonding and/or “feel” attributes of the joint compound.
