Abstract:
Methods of making calcium sulfate whiskers are provided. In one aspect, a method includes autoclaving a slurry of calcium sulfate hemihydrate and water to form calcium sulfate hemihydrate whiskers in water and microwaving the whiskers to dewater them, wherein the microwaving is effective to prevent a majority of the whiskers from reverting to a dihydrate form. In one aspect, a method includes microwaving calcium sulfate hemihydrate whiskers to form anhydrite calcium sulfate whiskers, wherein the microwaving is effective to remove a substantial amount of chemically bound water from the whiskers.

Abstract:
Building materials include a dampening layer which contains a plaster and a viscoelastic polymer, such as polyvinyl butyral. The dampening layer may also include a barium salt. Methods of making a sound dampening material include providing a plaster mixture. The mixture may include a viscoelastic polymer and/or a barium salt. The plaster mixture is combined with water and/or a viscoelastic polymer dispersion, to form a slurry. The slurry is applied to a surface and set to form a sound dampening layer.

Abstract:
Building materials include a dampening layer which contains a plaster, and hollow microspheres, such as polymeric microspheres. Methods of making a sound dampening material include providing a plaster mixture. The mixture may include hollow microspheres. The plaster mixture is combined with water to form a slurry. The slurry is applied to a surface so that it sets to form a sound dampening layer. Methods of dampening sound through a structure include disposing a dampening layer on a surface of or within a wall, door, floor, ceiling, roof, or floor/ceiling assembly.
