    Abstract: The invention generally provides gypsum-containing slurries including stucco, naphthalenesulfonate dispersant, and pregelatinized starch. The naphthalenesulfonate dispersant is present in an amount of about 0.1% -3.0% by weight based on the weight of dry stucco. The pregelatinized starch present in an amount of at least about 0.5% by weight up to about 10% by weight of pregelatinized starch by weight based on the weight of dry stucco in the formulation. Other slurry additives can include trimetaphosphate salts, accelerators, binders, paper fiber, glass fiber, and other known ingredients. The invention also comprises the gypsum-containing products made with such slurries, for example, gypsum wallboard, and a method of making gypsum wallboard.

    Abstract: A system and method for predicting wallboard fire performance in a standard test includes procuring a sample of the wallboard for testing, and mounting the sample into a fixture so that one side of the sample is exposed to a heat source. A cavity is created between the sample and the fixture such that the sample is disposed between the heat source and the cavity. A temperature measurement is taken at a predetermined location within the cavity over time, and the temperature is monitored and recorded as a series of temperature readings using a computer-readable medium. The series is analyzed to determine an index time at which the temperature reaches a predetermined temperature threshold. The index time is correlated to a standard-test fire performance using the computer-readable medium and, based on the correlation, a fire performance of the wallboard in a standard test procedure is predicted.
